Hello Upasana,
You must enter your aggregate marks up to last result or if you have passed your qualification examination then enter aggregate marks of your program. You don't need to enter separately. You can contact GATE Application help line through mail or phone number to remove discrepancy from your application. They can resolve your problem.
Good Luck.
