Which are the best MBA colleges in north India (Delhi NCR and Rajasthan)? I have scored less in CMAT exam.

What is your percentile?

You can find a lot of MBA colleges, but you should be very cautious about choosing the best, and for that, you should look at few things like the college campus and infrastructure, hostel facility, placement cell with placement record, etc. I would recommend, you should opt for UEM, Jaipur to fulfil

You can go for Jaipuria in Jaipur. They give less weight-age to scores. I would suggest you to give MAT in May and get better colleges.
