B.Sc Physics

It all depends on what you want to do. I mean which field you want to work in. There are people who like what they study and want a profession in their respective fields, while there are plenty of them who decide that what they study is not what they want to be the line of profession. If you have interest in physics, and you are good ATIT you can do Masters from good colleges like Indian Institute of Space Science and Technology or Indian Institute of Science. Also, you can apply for colleges abroad.
Note: It is really necessary to have a thorough knowledge of your subject and a lot of hard work to get into institutes I have mentioned. If you don't have interest in your subject and have interest in some other thing, It might be music, art, dancing, photography or any other thing, try to get some professional training in the same. Also, if there is any course for certification in the subject of your interest, apply for it.
