School
No donation. No interview. Ever.
No school can take a donation or capitation fee to give your child a seat. No school can test or interview you or your child to decide admission. A school that takes a donation can be fined up to ten times what it took.
College / University
They cannot keep your original certificates.
If you cancel your admission inside the window UGC sets each year, your fee must be refunded. And no college can keep your original certificates or marksheets — not to admit you, not to keep you, and not to let you go.
Coaching Institute
Leave midway, get the rest back in 10 days.
If you paid the full fee and leave the course midway, they must refund the fee for the remaining period within 10 days. That includes hostel and mess fees, if you paid them.
ITI / Polytechnic / Skill Centre
Fees in public. Originals in your hand.
An approved institute must publish its fee list, must not charge more than the state fee committee allows, and must not keep your original certificates. Leave inside the notified window and you get your fee back, minus only what the rules let them keep.
These are the national rules. Karnataka has its own fee law on top, and state fee laws differ a great deal — check both before you rely on either.
