Hello,

as per UGC guideline, exams will be conducted anyhow. No student will be credited to higher class with exam score.

your institute will also prepare to conduct exam so that you will appear all the paper including external, internal and lab. You have to appear all of it. on the part of backlog, your college/ university will release notice. You can check it and prepare accordingly.

in any case, you have to clear exam , it may be conducted online, offline or semi.

don't worry, you will get chance to clear your backlogs and appear regular semester exams too.

Hope it helps!
