Hi! As tanya said , marks wont judge your further journey in studies , so no need of worries if we get somewhat less results , as 10th results cant judge your life and your dreams .... Do hardwork in your coming up studies and do well n gud. All the very best ✌?

i believe marks are not that important ,ur knowledge matters a lot.if u consider urself good enough,have faith in ur abilities u actually do not need to think a lot about marks.what has happened forget that and just focus ahead because u have a lot more to do in ur life.so don't bother about marks.And its a good score if u trust urself.All the best for ur future✌
