Dear Aspirant,

There is no upgradation after the final seat is allotted to you based on the list of College choices that you have given and the rank that you have achieved.

Upgradation occurs only when there is some sort of temporary seat allotment. In case, candidates withdraw from the seat in a college which you have also given in a list of choices with a higher preference than the college allotted to you in the temporary seat allotment, then only you can get that seat if you have a good rank with respect to that seat.

In case of final allotment, there shall be no changes in the college allotted to a candidate in a particular branch. The candidate must download the final allotment letter and gather all the necessary documents required for OJEE counselling. Once all the documents are verified, only then it means that you have accepted the seat offered to you or else the seat remains vacant.

I hope you understood what you wanted to know. Good luck for your future endeavors and in your engineering career.
