Physics Spl

B.Sc in physics is a better choice. Computer application is taught in B.Tech in IT, CSE, BCA and MCA. Rest depends on your interest.

Yes, you can attend exams like above you mentioned but it is compulsory to get 75% in your 12th board and 65% if ST/SC candidate.

Sorry to say but your son haven't cleared JEE Mains required cutoff. So there is no way to get admission in any college through JEE Mains. You may get admission in any private college through 12th percentage.

After 12th, you will find very basic level jobs such as lab assistant etc or you can give SSC exams. But if you want a career fully in Physics then earn a bachelor degree and masters degree in Physics to open up opportunities such as teaching, research, astronomy etc.

You can get nothing unless and until you pass in all subjects in your 12th because I need to fulfill the eligibility criteria of the college for getting admission. Almost every college has an eligibility criteria of marks in 12th as 50% and above.

There are few companies which come to hire engineering physics students in core profile, Boston, Texas Instruments being some of them. Most of the students actually go for other roles such as coding or analyst and some of the students go for higher studies. Being a student of IIT Delhi myself, I know that students of this branch are not that happy with curriculum and unless they have deep love for physics, the students always try to get out of this world of physics.

To pursue B.Tech or any other course first you need to clear your 12th and that is why you need to reappear for the exam.
