Can I do MBA or mca after bsc physics?

Absolutely! Depending on the institution, the only thing that may be required are the prerequisites needed for this program of study. MBA candidates come from a variety of backgrounds, so yes it is doable.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
