Hello,

Its good to do study with physics. But you didn't mention that you want to do honours degree or another. Because you can study engineering and physics also including it. You can do physics honours and it's only the main subject of physics. After completing your graduation in physics honours you can go for MSc in physics and then go for PhD. So you are totally involved in physics.

In India so many colleges are offered physics honours. You have to score good in your 12th class and mathematics, physics, chemistry or biology or computer science is must in your 12th class. Then you can get admission in any Science degree colleges.
