Yes it's better if you know the basic mathematics atleast. Because in physics, in chapters like oscillations, work energy and power, circular motion, rotational motion, electrostatics, etc. you'll need to solve numericals where you'll need maths for sure. I mean if your maths is strong enough, things will work fast.

If you are planning on preparing for NEET, you cannot stick to one book because though the syllabus is the same, each author has his/her own way of depicting each subject. So you cannot just rely on one particular book. You can read MTG but that alone is not sufficient.

There are quite a few books available.The popular of them are:

NCERT Physics Class XI & Class XII
Concepts of Physics by H. C. Verma
Objective Physics By DC Pandey
Fundamentals of Physics by Halliday, Resnick and Walker
Fundamental Physics by Pradeep
Problems in General Physics by IE Irodov

Try to pay attention in your coaching classes or consult some professional. Also try seeing YouTube videos of PhysicsWallah... He explains greatly and in depth - all the concepts of PHYSICS. and once you are done with the theory of physics, start from little mcq books like Target and Marvel

Hello,

No you can't do that. Only Bsc in physics students can only  join Msc in physics. You have studied Btech then you can pursue Mtech in your branch only. You can't even choose other branch specialization. It has to be your branch or some way related to your branch.

Hey!There

Between Physics and chemistry,I will suggest you that you should focus on chemistry section more as you can score from chemistry because most of question of chemistry is fact and formula based,you can solve such problem in very less time.But you also need to score good in Physics t

Hello,  You should have to clear your 12 th with physics mathematics and English as compulsory subjects. But you should have to pass in all subjects. Minimum marks should be 50 percent. You must have to clear your chemistry.

I hope it will help you.

thanks.
