Yes, you can definitely appear for NIFT entrance exam after completing B.Sc (Hons) in physics.

That depends on the university you are applying to. Few universities have minimum 60% as the cut-off while others have 50% as the cut-off. For eg: DU has 60% as the cut-off, whereas, Manipal has the 50% as the cut-off.

If you are interested in physics, then go ahead. Don't be confused if you can do better in physics than other subjects, then you must go for the same.

Hello Vikas,
Of course, you can pursue B.Ed and become high school teacher but top level school prefer a PG graduate with experience. After B.Ed, go for TET.
All the best.
