Hello,
You must have at least 60%marks, if you are from General or OBC category, and 55%, if belonging to SC, ST and PwD. You should check one of the IIT websites for HSEE notifications.

JEE Mains and advance are just the exams to sleect meritorious students for admission in NIT IIT. To have your studies in any NIT, IIT you have to pay the fees accordingly.
I hope it helps.

See, if you want IIT you should give improvement. But if you hope for NIT you may or may not. Because rank is not affected by 12th marks. So decide wisely as you have to crack JEE Mains and good score in 12th. It's not difficult but you have to be dedicated. Think wisely. Good luck. Hope it helps.

For that, you have to visit the JEE Mains official website and go to the verification centre from there you can get to know where exactly the centre is.

Yes, you have to fulfil the eligibility criteria to get admission in IIT or NIT. 75% in HSc is the basic criteria.

You can only get NIELIT-Aurangabad, which is not a good college, but yes you can have a degree from government of India.
