Hii Yashvanth,

 as you have mentioned that you feild of interest is Engineering.

So you will appear in JEE main and Advance.

so you shoulh focus on Physics ,Chemistry and Mathematics.because in JEE main as well as in JEE Advance,weightage of these three subjects are equal.

so first of all you should clear all the basic concept of PCM(XI,XII) from NCERT.

and then you will have to focus on numericals mainly.

always try to solve previous year question bank.this habbit is very benificial.

If you are regular in Study then per day 2 hours for each subject will be sufficient to creack JEE main and For JEE advance,practice as much as you can.

here there are some books recomended through which you can read-

thank you                      

Hlo,

yashwant

I would like to suggest these books-

• Mathematics- NCERTand Rd sharma.
• Physics-pradeep,s publication /S.L Arora and NCERT.
• Chemistry- NCERT,G.R badla.

You should cocentrate on PCM  and concentrate more on your weaker subjects.

In 10+2 a student should studt  atleast 5-6 hours.split these hours according to yourself.

You should be consistent in your study .
