MNIT Jaipur - Malaviya National Institute of Technology Answered Questions

You can surely get MNIT but you may not get a branch of your choice. If you want to get a branch of your choice you will have to see for colleges lower in rank than MNIT .

The course which i am studying right now, i.e, B.Tech in Mechanical Engineering from MNIT Jaipur does include Automobile Engineering and is also very well taught in our college. Mechanical is an evergreen branch which means that a good Mechanical Engineer does not sit idle and always would be needed in future. hence in my view you should definitely opt for this branch. If you want to do B.Tech from Automobile Engineering solely then you could go for Delhi Technological University after your JEE Mains result is announced.

Most of the institutes (All IITs, NITs, IISC & other reputed colleges) use GATE score for admissions in M. Tech programmes. Some institutes (Mostly IITs) have the provision of 30% of marks in BE/B. Tech in final allocations of seats.
In MNIT, GATE score is used for admission but min. 6.5 CGPA is required (due provisions for various categories).
