I heard that if you're giving second attempt in gseb 12 board there will be 5% deduction for your total percentage is that true? please reply
As far as I have read, in order to appear for the second attempt, you have to submit your marksheets and a bonafide certificate. Once, you have submitted it, it would turn obsolete and only the fresh marks would be considered.
So if you are sure, that you can improve your score, then go for it.
Good luck.
