Hope this helps.

Well, you have to give good amount of time for NIFT preparation. Revise all basic Maths formulae, and practice questions, which will help you solve many class 10th level Maths questions. Be updated with current GK, not only national level, but with international events as well. Good vocabulary will score you much more. I would suggest, English is the main part of the paper that helps in scoring the most, so improve English grammar and vocabulary. You should have the basic knowledge related to history, geography, economics, and general Science up till class 10th. Go for aptitude books. Apart from this, you can download sample question papers online related to the drawing part, I. e, the CAT. It does't matter if you are not very good at drawing, what matters is your idea and concept you put into your sketch. You're given marks on how far you can think out of box. So practise this as well. And you still find difficult to decide how and what to prepare, go for any design coaching. All the best.
