GRE exam requires a minimum of three months of focused preparation. Practice is the key to get a good score in GRE. There are many GRE test preparation centers where the candidate can register and take Mock GRE tests to get a feel of the exam.

A good score in GRE is not the 'only criteria' of getting admission in the graduate school. Different schools follow different formula in weighing GRE scores to admit the candidates in the schools. For example some schools give more weightage to writing skills of the candidate in specific topic in addition to good GRE score. Keeping this fact in your mind, you need to perform well in all the sections of GRE exam.

Almost all the schools give high weightage to 'Analytical writing' section of GRE exam. Hence, do not ignore the writing part of the test, though you may be good in Verbal and Quantitative Section.

Avoid guesswork in your answers. GRE-CAT is designed in such a way that a candidate cannot 'revert' or 'return back' to a question like paper-version exams. So when the candidate clicks on the 'click-box' that will be his or her final answer. So, avoiding guesswork will always put you on safer side.

Avoid wasting time on answering single question or getting stuck-up with specific question for more time. If you don't know the answer of a particular question, move on to the next question.

Remember in math speed is very important. Hence rather than starting with tough problems first and worrying about maths and loosing confidence..practise some mid level question but under time pressure and as fast as you can and then move to tough problems ..because remember GRE is adaptive for you to encounter tough problems first you should pass easy and mid level problems first..the advantage of this approach will be visible to you when you are solving tests you will have more time to solve tough problems as the difficulty increases in the real test.

Plan your preparation schedule and stick to the plan without any excuses. Consistency in preparation and regular practice is the key to success. Have faith in your ability and do not loose your cool at any moment.
