Hi Vineet,
A candidate whose parents annual income does not exceed Rs.4,50,000/- is eligible for scholarship in IIT. So yes, you are eligible.

Hello Bharat,
The fee structure is different for different IITs. These are around Rs.70K per semester. Hostel charges are extra.

No, JEE registration will get over on 1st January. After that, you can not apply for JEE.

No, MBA in mining is a rare course and chances of getting a job are very less. Since you are a BBA graduate, you will be lagging behind the technical part of mining. So, I prefer not to take this course.

Check out the JEE Mains 2018 Eligibility Criteria to clear every single doubt coming in your mind.
According to this, the candidates who have scored at least 75% marks in the 12th class are only eligible for appearing in the JEE Mains exam.
So, if you can't appear in the JEE Mains exam, then you can can't get admission in any of the NITs or IITs.
If you haven't scored 75% in 12th, then you can go for the improvement exam or the NIOS exam.
Hope this will help.
All the best.
