Career

If you have opted for Mathematics at +2 then Engineering, I mean B Tech/BE may be an appropriate track for you. Besides you may also opt for B Sc in Sciences or Mathematics in case you happen to miss the engineering track. If you had Biology during your +2, you nay opt for MBBS / BDS / Ayurveda / Nursing / Agriculture etc, I mean Medicine. If you were Commerce group, then you may opt for B Com followed by M Com/MBA track.

Yes you can.it might be hectic. For IAS u need to be graduate first.

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.
