Hi Bhaskar,
Only students who have qualified the JEE Mains are allowed to sit for JEE Advanced. If a student wants to join B.Arch in IIT Kahargpur and IIT Roorkee, he/she has to first clear JEE Mains Parer 1 (not Paper 2 ; Paper 2 is only for admission to B.Arch in NITs and Spans). Also, Only those candidates who would have given B.Arch programme (available at IIT Kharagpur and IIT Roorkee) as one of their choices while filling their choices will be eligible to take the Architecture Aptitude Test.

Yes, you can do MBA in any stream that you want. There is no disadvantage, as you are doing it after B.Sc. And yes, you are eligible for IIMS also. For that, perform well in CAT exam.
