Dear aspirant!!

Hope you are doing well !

Well, some universities allow to do so while some not. We are it right people to comment on these things . You should always contact the concerned authorities of your college for these things . Most of the universities will  allow you to do so . You can repeat that 6th semester next year . But once contact your college

If you find any further difficulty , visit here .

Hope it helps you !!

Thanking you!

Have a great day !

Yes sir, if you get a backlog in any subject in your 6th semester, according to most universities you can reappear for the same exam next year with your 8th semester examinations. The exam fee charges would be as decided by your unversity or college(if autonomous)
