Dear student,

The major difference between a University seat and Self-finance seat is the difference of fee structures in both.

Actually , the university or regular seats are totally funded by the university grant commission  (UGC) and so the fee of such seats is comparatively low.

But, the self-finance seats are mot at all funded by the UGC and so to take out the expense of such seats and courses the university takes the help of students by raising the fee of self-finance seats. So, for such seats students have to pay more fees as compared to university seats.

Hope it helps!

Good Luck
