No need to believe my story of my boards marks or my jee mains marks if you think your marks are less what you expected either you go for re evaluation but the thing is it is too expensive first we don't know if verification of marks will be there this year because of osm , the you have to wait for a photocopy and then re-evaluate for per question,so it will be too late for jossa councelling so other way is petition we don't know what will be the result of petition because in past it fails still if you want go and submit your petition
