Hello,

I am attaching some of the advices by the people who have cracked the exam.

First and foremost, you must strengthen your math fundamentals. You may use YouTube to aid you with this. You may look for topic-specific mathematical lectures . Then, once you've mastered the fundamentals of math, try your hand at some problems related to the themes.Recommended books are

• RD sharma for Mathematics
• R.S.Agarwal for Reasoning.
• Arihant Complete study package for MCA

Then you may answer past years' JEE Main chapterwise solutions, which you can do by purchasing any book. After you've finished these books, you can use past years' NIMCET problems as a practise test by solving them in exam conditions. Then evaluate your strong and weak aspects and proceed with your preparation appropriately.

Hope it helped you
