What should I do?

What do you mean for a "section"? Do you mean a semester? A year?

If you are living in the college hostel, rent should not be an issue. If you plan to stay alone, you should find shared accommodation within the range of 2-3k. If you spend wisely and don't party every weekend, you can survive a month with 2-3k.

Considering you're a foreigner, local transport may be costlier for you, at least till you learn to argue and bargain with them, so let's keep .5-1k for that.

I would say, 6k a month should be good, but 7k would be better. You can lead a comfortable student life with 7k. I know students who live with 3k also. But their parents are at their disposal to send them money as and when required.

I would suggest you start off with a lower amount of 5k a month, see if you're struggling, then ask your parents to up your allowance by 1 or 2k.
