The GRE is now only available as a computer-adaptive test. This is how it works: instead of having a pre-determined mixture of easy, medium, and hard questions, the computer will select questions for you based on how well you are doing. The first question will be of medium difficulty; if you get it right, the second question will be selected from a large group of questions that are a little harder; if you get the first question wrong, the second will be a little easier. The result is that the test automatically adjusts to your skill level. The Tough questions have more credit than easier ones.
You can still earn a very high score even if you answer several questions incorrectly. Correct answers to Harder questions leads to large score as compared to easier questions. This means to Get large score more difficult questions has to be answered.
Some (Very few) Universities may demand Subject GRE.
After completing your exam you can send your scores (free!) to four Universities so be prepared.
Your GRE scores are valid for 5 years.

The Analytical Writing section is always first. For the Issue task, two topics will be presented and you will choose one. The Argument task does not present a choice of topics; instead, one topic will be presented.
The Verbal and Quantitative sections may appear in any order, including an unidentified unscored section. Treat each section presented during your test as if it counts.
