Dear Student,
It varies from college to college. Some colleges do allow applying to two or more than two courses through a single form but many colleges also do not allow application to more than one course through one form. In such case I suggest you to fill a fresh form for the other course you want to apply to. Private colleges like Amity University do allow to apply to more than one course through one form and many don't. Hope this might help you.

Dear student,
All the colleges have different criteria set for different exam forms. So you need to go through the official site of the colleges for accurate information.
Allthebest.

Dear student
It depends on the rules and regulations of a college.
Each college has a different pattern of admission.
Generally the form for two different courses is filled separately in almost all the colleges.
All the best
I hope it was helpful for you.
