NIT

Hello Nidhi, no one can stop you from learning something. Hence you can definitely learn whatever is being taught to the students of mechanical engineering of any college or university. For this you just need to approach the right teacher who can take you under the wings and teach you the rudiments of the subjects. Best wishes to you.

Looks difficult, you need to check the eligibility documents.

Hello Digambar, national testing agency has declared results of JEE Mains. They have also declared cutoff in terms of percentile for general and each catagory. This information is available readily on their website. I too can tell this if you can tell me your son's percentile and catagory. If his percentile us better than this then only he can seek admission in any NIT. Best wishes to you.
