Aim for a B Sc in Physics followed by Post Graduation in Astro Physics/Physics with a PhD. A few IITs and IIAP offer Integrated MSc PhD programmes.

If you have opted for Mathematics at +2 then Engineering, I mean B Tech/BE may be an appropriate track for you.

If you had Biology during your +2, you nay opt for MBBS / BDS / Ayurveda / Nursing / Agriculture etc, I mean Medicine.

Chances are really tough. In case you are from general category, then almost no chances. If you are from a reservation category, then still some. Chances, if you get a really good percentile

I hope you have 50% aggregate in +2 with PCM. You must clear national/state level entrance examinations with a good score as applicable to your institute/university. For admission to IITs and IISc you must clear JEE. Many private deemed universities conduct their own aptitude tests.
