Hi, 

Let me tell you something which is going to really help you. When we start preparing for any exam the most important question is which books to follow. Most of the students buy number of books and in the end get clueless. You might have heard that saying "Too many good cooks spoil the broth" and which is clearly not good. So get good books and clear your concepts first and then try mcqs from different sources. Ask your teachers, they will tell you which books are best for this. Firstly go through NCERT and then move to other books. This year too most of the questions were from ncert(biology).

Try MTG FINGERTIPS for mcqs. It is really nice. Don't run after many books. Get standard books and start studying. 

Good luck! 

Hi Aakash,

Reference books are not necessarily when you this much of study material.

I'll suggest that if you want to brush your preparation more then in that case you can purchase practise papers packages online. They are really helpful and will give a very wide idea of the paper pattern and types of questions.

Secondly you can also follow study channels on youtube.Some oonline portal also provide platform for queries and doubts regarding the syllabus.

All the best.

Not necessarily , you have to take a judgement call on this . I suggest if you are done with books that you already have then you should start expanding your horizons with sample papers and previous year question sets , make sure you observe the sort of question that comes in previous year papers analyse your weak point and work on it . 

All the best ,buddy !
