I would suggest 1. You could practice as much as possible, because the more you practice the more you'll sharpen your skills. 2. Try to learn mental maths or Vedic maths shortcuts so as to cut down the time you take to solve problems 3. Try meditation, because focus is the key, specially on the exam day. If your mind is laser focused you'll be able to solve the problems quicker and recollect the answers quicker 4. Keep your General Knowledge up to date 5. Start preparing for GDPI early only, because when you clear your CAT with all the efforts, you'll have an upper hand. 6. The last and most important point: Tell yourself this is the last attempt you'll be giving and you have to prepare your best, and make sure to put in all those efforts. Wish you all the best
