My issue with JEE and the entrance examination system as a whole in India is that it grades students based on a combination of just 3 subjects, physics, chemistry and maths. It dosent matter if you are passionate about computer science and you have the talent to code well, it won't get you a seat into the CS department at any IIT. Atleast it was like this when I was preparing for it. I don't know if the system is the same currently. It would be nice if there was some other optional exam that you could take to prove your competence in other subjects.
If you spend five minutes thinking about the problem at hand, you will yourself realize why things have to be the way they are.
Anyway, you can take heart in the fact that if your goal is just to learn programming, a computer science department at an IIT is probably the last place you want to be. I'm only half joking. The curriculum is tilted heavily towards theory, reflecting the attitudes of the professors who obviously come from an academic background (most of them have probably never programmed professionally).
There was only one course where anyone is actually going to even try to teach you programming, but that is actually a pretty basic programming course in the first semester. Everything else you are supposed to learn on your own, through "assimilation". There are several courses in your third year that require significant programming skills, so if you haven't learnt those skills on your own outside the classroom by that time, you're kind of fucked.
I don't understand why universities can't give a certain weightage to some specialized examinations. Like some international Olympiad for CS. We already have something like this if you are a KVPY scholar. But all universities only look at your entrance exam marks. Other than just trying to maintain the status quo I don't know why they can't change this current system.
Also even if the subject taught at IIT is not worth it it opens a lot more doors than what my college can ever do. In things like research.
