Hello

Ncert will actually help  to built your foundation  which leads you to get a good marks but its better to study more books to basically build  the unique thinking as well as problem solving skills which will not only in interview conducted.

Here are some the books you may go for :

For physics you can also go for HC verma

For chemistry you can also for op tandon books

For maths -RD. Sharma

For bio-k.n bhatia and trueman

Good Luck.

Hello

Chemistry is easy as compared to physics. You must have to clear the concept of chemical bonding, physical as well as organic chemistry. But NCERT is not sufficient. In case of biology most of the concept will get clear from ncert so you have to clear your concept and have to practice mcq .

Hope this helps

Thank you
