Hello friend,

During the time of correction you can correct the details like 12 th marks , photo, and other details but don't miss the dates because after that you won't correct that.

Hi, Most likely the percentage/marks you won't be able to change. The images are allowed to change. But it cannot be confirmed till the time information is officially declared.

Anyways it won't be a major issue. You can show your relevant proofs and documents at the time of admission counselling.

Good Luck.
