Hii Devyani Nigam..

What do you mean by minimum you mean "0".

You may get some timepass colleges which are money minded colleges(no education).

You need to think differently.

Make a plan what suits you. Take time on that and decide with one and go ahead.

If you purpose is for GRE then go ahead. Crack that with 320+

Many colleges provide good scholarships.

When you doing something in your life there must be a purpose don't waste your time having targets like "minimum marks" "easy money" that never happens.

"Hard work pays".

Hope you got it. All the best.
