DTU is not private but a government college. As a SC student, you can only get admission to DTU having rank up to 2 lacs in JEE Mains.

BMS (VTU based) but if you would tell which branch then it would be easy to guide you.

Marks required to be eligible for these is 60% but some colleges require only 50%. It may be 5% low for SC/ST.
So, try to get a minimum score of 60%.
All the best.

SIT-Tumkur is better in terms of placement, faculty and location.

Yes, Mangalore Marine College is good for marine engineering.

Hi Ashutosh,
Admission in IISC is done via 3 ways: first is you need to qualify KVPY examination, 2nd is you need to score minimum of 60% in JEE Mains and JEE advance and 3rd is you need to score minimum of 60 percentage in NEET. If you find your self in any of these category, you can apply for IISC

Hi Roshan,
Karnataka is not very much known for its mechanical engineering branch, but still, some of the best in its class colleges are RVCE, MVIT, MS Ramaiah, BIT, etc.
All the best.
