某些大學和專業要求申請者一定要有GRE專項考試成績，但不管要不要求，有條件的話一定要考一次GRE的Sub考試，一個良好的'專項考試能增加你獲獎的機率。現在大家所考的是Gerneral考試,Subject考試並不像大家想象得那麼難，只要花半年時間看看中文版教材，考前多做幾套SUB全真題，一般都會考一個不錯的成績。強調一點的是，準備SUB題一定要以全真題為主，事半功倍。
ETS會根據你的要求來決定是否在一般考試的成績單上顯示你的GRE專業成績。你也可以在考試結束後要求ETS取消這次考試的成績。
ETS推薦的專項考試準備技巧：
1. A general review of your college courses is probably the best preparation for the test. However, the test covers a broad range of subject matter, and no one is expected to be familiar with every question.
2. Use official GRE publications, published by ETS, to familiarize yourself with questions used on the GRE Subject Tests.
3. Become familiar with the types of questions used in the test, paying special attention to the directions. If you thoroughly understand the directions before you take the test, you will have more time during the test to focus on the questions themselves.
ETS推薦的考試技巧：
1. Read the test directions carefully, and work as rapidly as you can without being careless. For each question, you should choose the best answer from the available options.
2. All questions are of equal value; do not waste time pondering individual questions you find extremely difficult or unfamiliar.
3. You may want to work through the test quite rapidly, first answering only the questions about which you feel confident, then going back and answering questions that require more thought, and concluding with the most difficult questions if there is time.
4. If you decide to change an answer, make sure you completely erase it and fill in the oval corresponding to your desired answer.
5. Questions for which you mark no answer or more than one answer are not counted in scoring.
6. As a correction for haphazard guessing, one-fourth of the number of questions you answer incorrectly are subtracted from the number of questions you answer correctly. It is improbable that mere guessing will improve your score significantly; it may even lower your score. If, however, you are not certain of the correct answer but have some knowledge of the question and are able to eliminate one or more of the answer choices, your chance of getting the right answer is improved, and it may be to your advantage to answer such a question.
7. Record all answers on your answer sheet. Answers recorded in your test book will not be counted.
8. Do not wait until the last five minutes of a testing session to record answers on your answer sheet.
