Just be confident.
Some Pointers for the exam:
2.AWA:Don't strain yourself too much in this section. Use this section to compose yourself for the next two sections.
2. Quant: Expect tough questions in the beginning. Don't be startled. Maintain your calm and do your best. Even if you get one or two wrong, you still can end up with a score of at least 48.
3.Verbal:It usually starts of with some easy SC questions. Don't be complacent. Stamina is the key to Verbal. Give each question your everything. Also make sure that you have sufficient time for the last five or six questions.
All the best!
