The following result is obtained by our Real-time Research:
Chandigarh University is similar to any other private university, infrastructure is really good but academics are average. You must not rely on the university for academics. Like other private university CU focus in the advertisement, attendance and assignments.
For PGDM you must look for those colleges who focus on industrial exposure. Because PGDM is all about industrial exposure.
MBA from Manipal University is very less known, you may find difficulties in its industrial recognition. Manipal Academy of Higher Education (formerly Manipal University) is famous for its Manipal Institute of Technology (MIT) not for MBA. They usually treat their BBA and MBA under the same criteria.
Always choose those institutes for MBA, who treat MBA as their speciality.
