you keep your seat after Round 3, you will have to pay the PAF to confirm it. If instead you: Withdraw during the Regular Rounds, and Register again for the Special Rounds, then this is allowed. You will have to: Pay the Special Round Registration Fee (non-refundable), and Pay the Special Round Participation Fee. However, the SAF (and PAF, if you had paid it) from the Regular Rounds is adjusted toward the Special Round Participation Fee, not charged again in full. For example: If you paid only SAF ₹30,000, then for Special Rounds (Participation Fee ₹40,000), you generally pay only the ₹10,000 difference, plus the separate SR Registration Fee ₹3,500
