Mechanical Engineering

It will be ideal if you can do B.Tech as a lateral entry student. If due to personal reasons you can not study further, it is advised that you do AMIE along with job to have better career opportunities in future.

First let me ask you a question. What were you thinking when you chose commerce after 10th?

Nowadays, petroleum engineering can be considered the best in comparison with mechanical engineering.
Petroleum engineering has more job opportunities as there are less students in petroleum engineering than mechanical engineering.
Also it's depend on your own interest.
If you have interest in Mechanical Engeneering then Mechanical Engeneering will be best for you !
All the Best :)

When we talk about govt. institutions there's no better institutions other than IITs, NITs, IIITs, GFTIs because of its wonderful infrastructure, faculty, n placement programmes. Hope this helps u. All d best.
