Mechanical Engineering

Hello Mohan,
As per your rank, you will not get any good colleges. So, look forward for colleges via other exams. However, if you are inclined to take admission via IPU only then have a look over this for more insights.

CBIT does have management quota seats but they get filled up very fast. They usually have 10% OS seats but they change every year. I would suggest you to contact the concerned authority.

Of course mechanical, because after that you can go into production automobile robotic marine aeronautic etc.

For mechanical engineering in Pune University, you have the following options:
MIT
COEP
VIT
DY Patil
For chemical engineering:
DYPIEMT
MIT-Alandi

Akshay, to get admission firstly you must meet the cutoff score setup by the college itself. This varies every year. In Common Entrance Test, marks that you scored, cannot make you eligible for admission in good govt.colleges. However you can apply under reserved category candidate for govt. colleges. I would suggest you to go for some private college.

Go for Diploma in management and work in a startup. After that, you can pursue executive MBA with work experience.

Try for KSIT and DSATM.
