Hi,
If you don't want to study maths in 11th and 12 th standard the You can choose Arts or Commerce without maths. But choosing maths will be a better option.

For research institute, I would say he should go for B.Sc. If interested or IISc, B.Tech, IISER. To apply for B.Sc. In good Institution he needs score above 80% in 12th. And for other Courses like IISc and IISER he have to clear JEE Mains and Advanced both to get into IISc or IISER. For B.Tech, passing in JEE Mains is still okay. But for good College like IIT and NIT he have to clear Advanced or score above 150 in JEE.

If you are aware about the formulas and chapters of RD Sharma of class 11 and 12th, then you can complete them nearly in 2 months.

Both regular degree are not counted valid you can do HSC from open board or correspondence.

No, any student who has qualified 12th from science stream can apply for IISER.

Since you are from the commerce field, I would suggest you explore and research on ICWA and CA qualifications. If you are talking about the creative side of courses, then a lot of them in arts and craft, music, new language learning and designing can be done.
