I obtained 94.5% (best four) in the CBSE 12th, and I am having a one year gap. Should I apply for DU for BCom or go with symbiosis Pune/Mithibai or Mumbai? I have one compartment in maths this year. I am from the 12th CBSE board. If I give it, can I give improvement exam of 5 papers next year?  Will I be eligible for the JEE Mains and Advanced?
