Can reappear in graduation for last year(Or any year) in SOL, even if there is no backlog. (Motive is just to make percentage better) ?
As per the information available, yes you can appear for the Improvement examination but for that you can only improve your last given examination & all the previous year marks will remain the same. If you wish to appear for the Improvement examination, then you need to fill the Improvement examination form by visiting the official website of SOL, DU & only then you can appear for the improvement examination.
