Hello Shruti,

Improvement in quant will only come with practice. You can go back and refer NCERT books for quant basics. Initially, you can start with the topics that you are comfortable with and are easy for you. Slowly slowly you can increase the difficulty level. This will cover the difficult topics at the later stage but will help you to remeber them before exam.

Once you have covered all the topics, you can give as many mock examinations as possible for practice. This will prepare you for the actual exam if you carry out the analysis in detail for each mock that you have given. Try solving those questions which you could not attempt or were difficult to you. Mock analysis will help you to cover maximum of the syllabus.

Good Luck.
