Hello Sanju,

You cannot submit your improvement marks in the keam rank allocation. The marks you have submitted in the beginning of the exam will only be considered in the allocation of your rank for the keam. But you don't need to worry about it as only certain percentage of your HSE score will only be added and maximum of you keam marks will only be considered in allocations of ranks. So, doing better in keam will help you in acheving the good rank.

Good Luck! will be happy to help you with ay other doubts.
