Salina ;

I totally understand your concern but you should not worry too much about it. You have already attained the certificate with 57% in PCB. So, now if you get the seat in NEET you will have to provide the 57% certificate and ignore the improved certificate during the counseling procedure.

The improved certificate will hold no value there. You should ignore that during counseling. It will cause you no problem as you have already attained 57%. So, that will be enough.

Hope this helps!
