GRE, full name of Graduate Record Examination, the Chinese name for the U.S. Graduate Record Examination, apply to a business outside the law and professional. By the U.S. Educational Testing Service (Educational Testing Service, referred to as the ETS) sponsored, GRE is the United States, Canada, Graduate School of the University of all kinds (except for Management, School of Law) requires the applicant must have a test scores,UGG Outlet Online, but also professors whether the applicant is awarded scholarship based on the most important criteria. Otherwise, Generic Routing Encapsulation (Generic Routing Encapsulation) is also referred to as the GRE.

Then held each year in many parts of the world. China is responsible for the coordination of foreign examination and centralized management of China and other foreign contractors GRE exam.Some prestigious universities in the United States special GRE scores as a Then if GRE scores are useful to provide special help for scholarship funding. Therefore, if the applicant sufficient time if more, it may participate in the special examination, a good GRE scores are able to reflect the specific applicant's professional qualities and learning potential. GRE General Test is necessary to apply for graduate school exams, law or business school graduate to apply to LSAT alternative GRE General Test or GMAT. Currently on the American University in alternative performance requirements than ever loose some. Many schools can provide GRE General Test or GMAT test scores of any class of graduate students should be provided as a commercial success, the law graduate is also an alternative to GRE General Test scores LSAT results. Training institutions with the increase in students studying abroad, gre training institutions have gradually increased. Among them, the Beijing New Oriental School has 17 years of training experience, have occupied 70 percent of the overseas training market, in training students to reach 450,000 people, with a wealth of teaching experience and cutting-edge materials to help students overcome difficulties GRE, were stationed in the United States the school. Examination form examination form domestic mainland China, Hong Kong, Macau, South Korea, the current implementation of separate examination form. By the machine test (Analytical Writing) and written (language, mathematics) composition. In addition to the examination form in other parts of China mainland-based test area, the current implementation of computer-based test (analytical writing, language, mathematics) in the form. The scope of GRE GRE (Graduate Record Exam) for addition to the legal (required to attend LSAT test) and business (subject to take the GMAT test) outside the range of disciplines and professional postgraduate examinations. Two types of GRE test (usually referred to the GRE are referring General test): general ability or inclination test called (General test or Aptitude Test); said senior professional test or quiz (Subject Test or Advanced Test). Candidates need to apply their own conditions and requirements of the school to participate in one or two exams. General purpose of the examination: According to the basics of college graduates and ability level, the candidates engaged in academic research in the advanced stages of the general ability to weigh the potential, without addressing the specific requirements of any professional. Professional examinations, the aim is to test candidates in a particular subject area or areas of expertise acquired in the knowledge and skills and level of ability. About the latest changes in the reform of the GRE ETS will launch in August 2011 the new GRE test. The examination focused on three areas of reform 1. Test content 2. Examination form 3. Calculation method of the following points to be discussed from three aspects: writing writing part of the study will focus on the targeted candidates ability to respond to specific questions, rather than require candidates to a pile of general text. Specifically, these include a clear focus on the ability to articulate complex ideas effectively using appropriate examples to support ideas of common sense and inspection / verification and related arguments to support the arguments of others targeted a coherent discussion control standards in writing some of the various elements of writing in English will jointly examine the logical reasoning and analytical writing, two skills, and will intensify the introduction of candidates who need to make a targeted response to the exam, candidates rely on pre-reduced preparation (such as recitation) of the material may of. Language skills of language study will be more emphasis on higher cognitive ability, and strive to be more in-depth and truly reflect the candidates' understanding of reading material and reasoning capacities. Specifically, these capabilities include the analysis of a discussion text and derive conclusions; According to incomplete data do derive; identify the author's premise / assumptions and perspectives; understand the meaning of multi-level language, including literal meaning, the meaning of rhetoric and purpose of such selection of important authors point of view, the main difference between discussion and secondary / related discussion; concludes the paper; understanding of text structure to understand words, sentences and paragraphs, chapters meaning; understand the different relationships between words and concepts emphasize complex reasoning more prominent high-level cognitive skills more context-based understanding of, for example, a simple vocabulary for reading comprehension to reduce significantly (by rote vocabulary acquisition) of the study, the abolition of analog and anti-sense questions to expand the article a new topic choose the surface type and new skills from the article, select a sentence, plus the amount of math to answer questions and concerns before the math part is still the same mathematical concepts, but will introduce more and more prominent scenes of life on the candidates ability to interpret the digital examination. Mathematics, including the ability to read some of the concerns quantitative information and analysis of quantitative interpretation of information using mathematical models problem-solving arithmetic, algebra, geometry, probability and statistics in the basic concepts of quantitative reasoning ability and skills to improve life stress scenario questions the proportion of questions and data interpretation to provide online calculators to reduce the amount of new kinds of questions and new computing skills to type a numerical answer to ETS believe these improvements will help to better test the future of all the candidates (in graduate school) the potential for success. (Beijing New Oriental School Examinations GRE test study of foreign central authority to provide) GRE exam registration process and preparation before the exam registration: registration procedures, and reading to prepare the computer to complete online registration. Registered Users: If the candidates have never used a GRE registration system, you must first register as a user. Fill out the Registration Form: Select the Pay: In the There are two payment options: online payment and electronic funds transfer. GRE Application Process 1. Download and read the Handbook for Candidates (GRE Bulletin of Information) and add inserts (Supplement) 2. Online pre-test position 3. Online or pay examination fee (paid online real-time use of business lines and Merchants Bank online payment platform; under the net payment at any bank wire transfer to the examination fee NEEA designated bank account. Examination fees for the 1460 yuan , (online payment of examination fee plus 6 yuan fee, examination fee under the net pay plus bank charges 14.6 yuan. 4 candidates within the specified date, I went to the point of filling the application form candidates must carry pre-test bits with valid ID. 5. Candidates I sit by the date specified in point to collect admission ticket, you must carry 2-inch recent photo without hat and valid identification. GRE exam GRE exam is divided into two parts, written and drive test, the written part of the June and October each year Examination, candidates must complete before attending the written part of the machine again. to 2009, for example: participation in October 2009 written test shall be July 1, 2009 to September 19, 2009 complete machine test part of the test (note: national holidays are not arranged examination). written in October 2009 in time for October 24. to participate in June 2010 written test shall be September 20, 2009 to 2010 May 8 complete machine test part of the examination (Note: The national holidays are not arranged examination). June 2010 of the written test time for June 12. GRE exam period starting five years from the effective individual professional requirements of individual schools GRE scores within three years, we all need to find this. examinations are two types of GRE test, said one general ability or inclination test (General test or Aptitude Test) test or said second high-level professional test (Subject Test or Advanced Test ). GRE also Writing Assessment, the Writing Test (CBT), is already a compulsory project. General test GRE General Test is to examine the main examination of basic English skills and knowledge of English involved in the breadth and depth, large Some Chinese students have participated in this examination,UGG Outlet, including paper-based Verbal, Quantitative two parts, are 800 points out of a total of 1600 points, the results five years effectively. GRE General Test will take three hours, a total of four parts, all multiple-choice questions, wrong answers do not fall points to implement the method. four-part exam is two parts content vocabulary items (Verbal), two items belong to mathematics (Quantitative). vocabulary item takes 1 hour, includes four questions ① complete sentence reading comprehension ④ ③ ② analogy antonym, which completed the sentence, analog and antonyms are words in the test for understanding, reading comprehension is the examination of candidates with the thrust of the article to understand the logical structure, the article may be involved in any scientific field, but the biochemical, astronomy, literature, geography, history, mostly. vocabulary major testing candidates is understood in terms of breadth and depth of understanding, so Chinese students scored very low in this area, but this does not apply for scholarships great impact, because ETS GRE scores are clear on the explanation: be affected. examine the applicant's GRE scores should be used as a standard audit of people's experience, should not adopt a uniform minimum admission criteria strictly for English language proficiency test and another TOEFL TOEFL score over 550, (550 U.S. universities that TOEFL score proves candidates with high proficiency in English to understand, and that the candidate be able to fully adapt to the teaching of English in the United States, the U.S. national average of high school graduates take the TOEFL score is also Only 580 points), there is still a great opportunity to get scholarships. mathematical item takes an hour, consists of three problems: ① ② compare the number of separate diagrams to explain the number of ③, covering arithmetic, algebra, geometry of the basic problems Chinese high school used only learned the content, topics are more easily, so most Chinese candidates can be very high in math scores, quite a number of test to score 800 points. Subject Test GRE participate in the special examination Chinese candidates are not many, because most American colleges do not require special GRE scores, GRE scores only requires ordinary, but the applicant applying for graduate and undergraduate professional inconsistent applicants are required to provide special GRE scores, for example A king in China won a university bachelor's degree in physics, hopes to change the read the U.S. economy a master's degree (Master of Arts in Economics), then you need to provide special economic GRE test scores, if you want to change to biochemistry degree, you need to provide specific biochemical GRE scores If the undergraduate application for graduate study and professional expertise with the same, generally do not provide specific results. GRE subject tests, including mathematics, chemistry, biology, physics, biochemistry, computer, psychology, English literature exam seven exams. examination structure at present, GRE CAT written examination the same ideas and the contents are similar, but the subject has a significant distribution and order changes. CAT 4 or 5 Section, Section, but only three points, Verbal, Quantitative, and Analytical in depicting a Section. Section excluding experimental results, but I could not distinguish the first Section, excluding a few points, so seven to answer some questions should be careful. ETS familiar with equipment to allow candidates to the examination room (highly recommended!) uncertainty due to the structure of the total examination time variable, usually no more than 4 hours. test the whole process is as follows: · Tutorial - Computer counseling practice, time limited to background checks Verbal language, 38 questions, 30 minutes - scoring Quantitative Mathematics, 30 questions, 30 minutes - total sub-Identified Research Section - may appear, usually a Mathematical Reasoning, and will be the last part, do not choose to keep score or disqualified choose to submit scores schools, up to four questions specific distribution: · Verbal Question 1 - Problem 7: fill in the blank sentences, each question there are empty entries 1-2 Question 8 - Question 16: analogy, there are five options for matching the first 17 questions - 27 questions: read (a long text, an essay) 28 questions - 38 questions: antisense, 5 words or phrases from the filter options Quantitative questions - 1 Question 15: Number 2 compare the size of the first 16 questions - 20 questions: 21 questions Computing and Applications - Title 25: Chart reasoning GRE Writing Assessment is generally not more than 2 hours, the examination is structured as follows: · Tutorial - Computer counseling practice, time limited Task 1 - 30 minutes with no rest Task 2 - 30 minutes GRE Subject Test GRE is divided into professional examinations in mathematics, biology, physics, chemistry, history, music, French, Spanish, computers, economics, engineering, education, geology, American literature, political science, psychology and sociology, The number of questions in various disciplines and different forms, its main purpose is to test candidates in a particular subject area or professional field of knowledge and skills acquired and the ability level of (1) math class (M67 ─ ─ Mathematics) about 66 questions, questions mainly for graduate students want to study mathematics candidates, focusing on the mathematics knowledge and skills in addition to the basic calculus, but also including linear algebra, mathematical analysis, to require candidates to be able to learn by analogy. about 1 / 4 of the questions related to the complex variable analysis, topology, number theory and other aspects of knowledge (2) physical class (P77 ─ ─ Physics) of about 100 questions, which mainly deals with the physical courses university of which about 20% of classical mechanics , electromagnetic base about 18%, about 10% atomic physics, physical optics and wave phenomena accounted for about 9%, fluid mechanics and statistical mechanics about 10%, about 12% of quantum mechanics, special relativity about 6%, the experimental method of accounting for 6%; the remaining 9% mainly related to the content of modern physics, including Lagrangian and Hamiltonian mechanics, atomic and proton physics, low temperature physics and space physics (3) chemical class (C27 ─ ─ Chemistry) about 150 questions, covering the major contents of the Chemistry course which, account for about 15% of analytical chemistry, inorganic chemistry about 25%, about 30% of organic chemistry, physical chemistry, about 30% (4) computer science class (C29 ─ ─ Computer Science) of about 80 questions, involving the University of electrical engineering and computer science courses, of which software system and method of approximately 35%, about 20% of computer architecture, computer theory, about 20%, accounting for Computational Mathematics 20%; other areas such as mathematics and simulation of transverse-type accounts for about 5% (5) biology class (B24 ─ ─ Biology) of about 205 questions, divided into a total of three parts: the cell biology and molecular biology of organic human biology, including ecological learning and evolution (6) Engineering (E37 ─ ─ Engineering) of about 140 questions, covering basic and specialized university foundation courses, including mechanics, heat transfer, electronics and electronic circuits, thermodynamics, material properties, etc. in the individual questions may also involve chemical, engineering evaluation, optics, acoustics, computational methods, engineering economics, fluid mechanics, hydraulic principles, etc. are about 50 questions related to the application of mathematics, which studies a class of questions from the application of mathematical models to project to complete by operation; the other questions from the study of intuitive mathematical concepts, find the best way, and then applied to engineering practice.

This book has changed seven times, until the collection of the GRE in June 2004, all the important terms, including the GRE often test the analogy vocabulary, antonyms, fill in the blank vocabulary and reading vocabulary. a detailed explanation of the memory of every important word method, in addition to roots, affixes memory method, the analysis of associative memory method, pronunciation mnemonic are also the characteristics of the book, boring into a vivid memory of this game. classification: number of words are marked * GRE analogies, antonyms, words in the test is too important not to fill in the blank and the word * the word. did not put the analog problem of testing questions word back, candidates master the words, the way to actually do the theme of skills to master the analogy questions. comes standard U.S. tone MP3 CD-ROM, with the learning, the better. In addition, the book is not with the tape 6, prices do not of dollars. This book features features <1> quality-tested GRE vocabulary book this book affects hundreds of thousands of GRE candidates, all the students carefully back over the book, are in the GRE test achieved excellent results. Features <2> new Select At the same time increased in recent years, there have been examinations of new words, so keep pace with times. Features <3> the book is divided into three parts: Part I: Part II: Select method has become the mainstream of Chinese students to remember the word method, in which memory is associative memory and pronunciation of the original book, these methods make the memory of English words into servitude by the boring of a lively game, greatly overcome the words of the students back fear, and enhance the memory of the word fun and improve the learning efficiency of the memory of the revised method of making the book a certain degree of adjustment, the memory of the modified method is more appropriate, closer to life. Features <5> GRE vocabulary selection Features <6> often fill in the blank test of the word or read the words so that students can be marked on the back * number of words, and must memorize, and then back marked with an asterisk is not the word, leaving the more profound these words in memory, in response to fill in the blank reading or a new analogy, antonym questions. entry under the derivative, the same root word other items are carefully recite the student test scores, statistics show, and back marked with an asterisk GRE vocabulary words is difficult to get high score The for word prediction, students do not have to do too much of their analysis, see more before you can Linkao Features <7> reference dictionary of commonly used ETS topic and Merriam-Webster, New World Thesaurus, NTC's Dictionary, etc.; the same time, after comments in English with the GRE test often synonymous to the word purpose of the joint memory Features <8> The real problem analog realm, to fully enhance the ability to do analysis to determine the theme. Generic Routing Encapsulation (GRE: Generic Routing Encapsulation) Generic Routing Encapsulation (GRE) defines a network layer protocol in any package on any other network layer protocol of the agreement In most routine cases, the system has a payload (or load) package needs to be encapsulated and sent to a destination. The payload is first encapsulated in a GRE packet, GRE packet can then encapsulated in some other a protocol and then forwarded. protocol is called the delivery protocol when IPv4 is used as the GRE payload, the Protocol Type field must be set to 0x800. When a tunnel endpoint decapsulates IPv4 packet as the payload of the GRE package, IPv4 destination address in the header must be used to forward the packet and the need to reduce the payload packet TTL. It is noteworthy that, in forwarding such a packet, if the packet's destination address payload is encapsulated packet (also is the other end of the tunnel), looping can occur in this case, we must discard the packet. when GRE packets are encapsulated in IPv4, you need to use the IPv4 protocol 47. GRE and conventional network security under the IPv4 network security is more similar, GRE using IPv4 routing under the original use of the route, Route filtering will remain unchanged. packet filtering firewall requirements of the GRE packet, or the GRE tunnel endpoints to complete the filtering process in which this issue was seen as a safe environment , you can terminate the tunnel on the firewall. GRE About GRE (Generic Routing Encapsulation, Generic Routing Encapsulation) protocol is a certain network layer protocols (such as IP and IPX) encapsulation of data packets, these packets are encapsulated to another network layer protocol (eg, IP) transmission. GRE using Tunnel (tunnel) technology, VPN (Virtual Private Network) tunneling protocol of the third layer. Tunnel is a virtual point to point connection, provide a a path that can be encapsulated data packets transmitted on this channel, and a Tunnel at both ends of the datagram encapsulation and decapsulation. an X protocol packets across an IP network in order to transmit in the Tunnel, must be Encapsulation and decapsulation through two processes: 1 plus the packaging process?? Router A Connect Group 1 of the X protocol packets received by the interface, the first by the X protocol processing?? X protocol packet header checks the destination address field to determine how to route the packet?? If the packet destination address to go through the Tunnel to arrive, the device of this packet to the corresponding Tunnel interface?? Tunnel mouth after you receive this message GRE encapsulation,Moncler Shop, the encapsulated IP header, the device according to the IP packet's destination address and routing table to forward packets from the network interface to send out the appropriate. 2. GRE encapsulated packet format GRE encapsulated packet format is: [Delivery header (Transport protocol )]--[ GRE header (Fncapsulation protocol )]--[ Payload header (Passenger potrocol)] need to package and transmit data packets, called the payload (Payload), payload protocol type passenger protocol (Passenger Protocol). system receives a payload, the first use of encapsulation protocol (Encapsulation Protocol) for GRE encapsulation of the payload, that passenger protocol packets of the a GRE packet; and then encapsulated original packet is encapsulated in the GRE header and the IP packet, so you can complete this by the IP layer is responsible for forwarding the message forward (Forwarding). Usually this charge prior to forwarding The IP protocol called Transport Protocol (Delivery Protocol or Transport Protocol). according to the different transport protocols can be divided into GRE over IPv4 and GRE over IPv6 two tunnel modes 3. decapsulation process solution package during the process of packaging and processing On the contrary.?? RouterB receives from the Tunnel interface IP packet, checks the destination address?? If the destination is a router, RouterB strips off the IP packet header, to the GRE protocol processing (to test the key, check the checksum and packet sequence number, etc.)?? GRE protocol to complete the appropriate treatment, stripped of the GRE header, and then by the X protocol for forwarding packets for subsequent processing. Description: GRE Encapsulation of both sending and receiving, decapsulation processing, and packaging caused because the amount of data increases, the device will result in the use of the GRE data forwarding efficiency decreased to some extent. GRE test scores ways to search for overseas candidates must be within the same stage of the three-part test (logical composition , Language, Mathematics) completed the essay portion of the machine test and language, mathematics, paper and pencil test to get some results in the paper and pencil tests after six weeks, ETS GRE Test Report Form will be sent. extended reading : 1
