Biotechnology

First, you should decide whether you want to go in private or government. If government, then it will not be so expensive. That will cost around 1 lakh (lodging + fooding). If private, it depends on college, but I will give you an idea that, it will less than equal to 2.5 lakhs per year including with your lodging + fooding. Go ahead because Biotechnology is our future. In coming days, you can do a lot with it.

Physics is a base of engineering. If you don't like physics. And go for arts and commerce.
