Gujarat

You should choose some government university for distance MBA rather than private ones. Also, take care that the university is in Gujarat itself or else it should be central university. My recommendations are IGNOU, University of Madras and Pondicherry University. These central universities have study centers across the country. Don't choose private or universities owned by other states, it might be risky.

You need to crack JEE main with good score for it.

No NIT offers B.Tech in mechatronics. If you want to pursue this course then check out private universities.

Hi Parth,
You can get Shanti Business School with this score. It is one of the best management institute in Ahmedabad. Apart from this, you can try for MICA.
All the best.
