Certificate

In my opinion there should not be. They will look for you graduation certificate when going for the job and if you are eligible for admission in ba llb then it wont be a problem in future regarding this

I would suggest you focus on successfully completing BDS and thereafter you can plan for certification course in nutrition.

Yes, you can do certification in nutrition now

Hello Harshal,
For JBIMS, this year the cutoff for OBC was around 99.50 percentile. The fee is 3 LPA for General Category and 1 LPA for all other reserved categories.

For sports quota, your percentage doesn't matter but you need to have maths as a subject in your +2.

Yes, you should necessarily have that B.Ed and graduation certificate. At the time of application, they are not asking for it but if you qualify the entrance, then you have to present it for sure otherwise they will cancel your candidature. And if you are a final year student of B.Ed you can apply for CTET this year also.
Regards.

You can't do both the courses at same time because both the courses are regular and regular courses can't be done at the same time.
