Hi Dear,

Yes, you need to apply to different colleges accepting CMAT to be eligible for admission in those college. Also, you'll need to pay fees separately for each college you are applying. CMAT score helps you getting admission in the colleges applied in order to meet the cut off and be eligible for further rounds of selection like GDPI etc. Also, just applying to colleges. do not guarantee you call or selection to that college. Each college will declare there call letters after considering your overall profile. And then you'll be eligible to sit for further rounds of selection.

Good Luck
