Hello aspirant

yes you can apply for the CET -MBA exams , due to corona all the institutes are facing difficulties in conduction exams so there will be no problem when you will apply for the CET MBA exam, you will be asked to submit your grade report and provisional degree certificate once it is arrived from the university till than your admission will be on the basis of an undertaking and I guess till the 7th semester's results, once your 8th semester's exams are held you will be asked to submit the final grade report and don't worry enough time will be provided to you for doing so.

I hope it helps.
