Hi aspirant, 

Normally admissions are done on the basis of 10+2 class result in board exams or by national level exam or common entrance exam conducted by the college. Deemed universities and private universities have the same eligibility criteria by taking exams. Deemed universities have less fees than private colleges (generally).

If you would mention the name of colleges then it will become easier for me to explain you the fee structure of that college.

Hope it helped. 

Good Luck.
