Private colleges generally have 3 kinds of seats - 

1) Government quota seats 

2) Management Quota seats 

3) NRI quota seats 

The fee varies for each type of seats.

NRI seats > management seats > government seats. 

However in deemed universities you have two kinds of seats only - NRI and management quota 

At the same time you should know that lower the marks, more the fees since you may not get admission into a desired private college as well if your score is less.
