Keep following things in your mind.

1)You need to be regular to your coaching.

Hello Ishaan, As you are saying that you have joined coaching. So, I would suggest you follow the booklet provided by your coaching for reference because the booklets have the best questions collected from everywhere. So, you don't need to look into any other books. You might read one or two topics from another book but don't read multiple books at once as it will only create doubt. Also, Have a fixed routine of revision of everything taught in the coaching that day because revision is very necessary in order to understand the topics. Don't study new concepts at the end as it can create nervousness in the end.
