IIT

Before class 12th and after class 10th, you have to join IIT coaching centre anywhere in India where it is suitable for you. It is a 2 year coaching course and in class 12th, you will have to give JEE Mains. And, if you pass it, then the second exam would be JEE Advance. If you are a CBSE / ICSE board student, then you can do self-study without coaching, and if you are state board student, then you need coaching. After you pass Advance, you will get a college according to your rank in JEE Advance.

Hi Sanketik,
For getting any of these branches in any of the IITs, you need to get rank under 5000, for which you need around 160 -170 marks in JEE Advanced.
Best of luck.

It is not necessary to join IIT to become a game or software application designer. B.Tech CSE/IT or MCA from a decent college with good development experience is the foundation step to become a designer.

The maximum coaching classes are from 3-9. However, Resonance is a better option.

It is about 8-10 lakhs.

Yes, you can get admission in an NIT.

Dear,
Think and judge yourself. Are you really interested in Science & Mathematics! If so, go ahead with all your efforts to shape your dream. If others are your very close, convince them with your JEE result. Best wishes.

Hello Priyanka,
I think PrepLane app is the best for online questions and tutorials. It is far better than other apps. I used it and I'm highly satisfied. Rest choice is yours.
Good luck.

You may try in some institutes other than IITs which accepts advance scores like IISC0Bangalore, IISER, IIPE, IISST, RGIPT, etc.

To get into IITs you must secure above 110 marks in JEE Advance.
