Iam student of class 11th and I want to know how to prepare for jee exam

Aditi Amrendra Student Expert 6th Dec, 2019

Hello,

First of all give you most of the attention to you class 11th study.
After that start with the syllabus
1. Analyse the syllabus wholly.
2. Highlight the topics which you haven't read yet, abd you don't have any idea of that and start with them.
3. Make a routine and divide the timing for everything equally.
4. Since you are in 11th, everything would seem to be very new to you. So start with a basic book, I would suggest for the very recommended NCERT for physics and chemistry.
For maths, practice from R.D Sharma or RS Agarwal.
5. After completion of every chapter, practice previous years questions.
For physics, i would recommend you to study and practice D.C Pandey.
For chemistry, NCERT+RC Mukherjee(physical)and this would suffice.
After, completing your syllabus start giving test series of a good institute.

We are providing online package for preparation for JEE mains.Reccomneded by toppers and designed by faculties with 15+ years of experience .
