Dear,
I believe that no student is bad or average. It is the failure of the teachers concerned who failed to motivate a student and making him really interested. If you can motivate yourself internally and aspire to have an in-depth knowledge of physics and have a dream to go ahead with Physics. I think you can pursue Physics inatUG level. Your success in Physics awaits.
All the best.

Whereas, Mass Communication is related to the application of such principles and formulas for solving problems which prevail in the society.
