Greetings!

I don't now about optional subject selection. your help will be appreciated if somebody take initiative in below mention case,

Can I select optional subject from any group, means two subject from one and the one subject from the other group?
Actually I want to take optional subject physics, pure math and Applied Math.

Moreover I have done master degree(M.Sc) in Applied Physics

Thanks in advance,
