IIT Eligibility

Yes, definitely, everyone can do study from IIT but its tuition fee is high about 1.17 lacs per semester. Overall, the tuition fee for a year will be approximately 2.35 lac rupees. But there may be a concession of 70% tuition fee if your family income is less than 4.5 lacs. So, it's good for you dear.
Hope this helps you.
Thank you.
Keep asking.

No, once you have taken admission in any of the IITs, you can't take JEE Advanced again.

Yes, sure. The eligibility criteria is a minimum of 75% (overall) in class 12th with PCM as a mandatory subject. Make sure you work hard so that you could qualify with very high marks in your respective category, so you will able to get a good college via JEE mains in one attempt.
Best of luck.
