Pls help me with this guys

Can I add bio or hind. Music vocal marks, instead of chem..and still get btech(any branch), in cse manipal

With chem it's 76.5%, with bio, it's 77.5%, with hind. Music vocals will most definitely be above 80% ...PCME scores

Also how many marks do I need to score in met, to secure cse in mit manipal.

Please answer fast

Thankyou
