Kapil,

I would suggest you to take admission in University of Delhi as they have direct admission where you can skip the entrance part. If you manage to get your best four in the cut off you would be selected and have the course of your choice.

If not then you even try colleges like Amity or else you can try distance learning college like IGNOU.

That actually depends upon the place and the college.

If you are in kolkata then xaviers kolkata is the best but for that you need an entrance which is pretty hard as in that test includes gk english maths(basic level) ad other. But for other colleges here as in Heritage and others there is no such entrance test
