what is the percentage of increasing marks in physics,zoologyand chemistry when we apply for re verificaton

Dear Akshita ,

I hope you are doing well !

If you are applying for re-verification or re-checking then how much percentage or marks will increase its totally depends upon board and papers those are checking your paper.Mostly 1 to 2% increase and might be maximum but some of time marks are also decrease .

If we go through live example then ,im former b-tech student and in my second year i apply for recheck in one subject but it was not increase the grade it was decrease .

Its not mean i lose your confident or hope it is the real fact of board .

I hope it will helpful

Thanks
