Distance/Correspondence

Hello Rishabh,
It's indeed very nice to see your enthusiasm for studying. You can download the application form of Mumbai University & I would advise you to download same of IGNOU also. Then you can decide which course to select. Normally, 12th is the eligibility. Check if these two accept Diploma as equivalent to class 12th. If not, you will have to complete class 12th. This you can do from NIOS.
Best wishes.

If this is a recognised degree then there won't be any problem.

There are many courses after class 12th Science. If you have completed class 12th Science in biology, then the best option for you is MBBS. Besides MBBS, you can also do BHMS BAMS BNYS, Bachelor of physiotherapy etc. And, if you have passed class 12th with Maths, then you can do engineering. Moreover, B.Sc is also a good option for a Science student. So, it's your choice, what is best for you.
