Udaipur

All Good. But, not for serious learners, classes are not regular and affiliated. Colleges doesn't have regular attendance. It is good for those students, those just want to earn some degrees. It provides a wide range of programs but one should study from his own end and should not totally depend on the University. University of Rajasthan is also good for distance learners because they just need to pay exam fee once enrolled. And, syllabus is easy and scoring good is not very hard. Overall, the university is good from facilities point of view but from academics point of view it is quite okay.
Choice is yours.

It's worthy. But you have to build your self-capacities. Because MBA from a private institution means you are a job seeker. So building your self-capacities will help you to get a good placement quickly.
