Hi Aditya,

It's a private B-school approved by Council of Higher Education. It's certainly not a very renowned B-school though. The institute accepts CAT score (not mandatory) for admission to its various PGPM programs. The institute also conducts its own entrance exam Regenesys Management Admission test (RMAT) for admissions. You can refer to its official brochure available on the official website of the institute to know more about the admission process.

To know more about the institute in detail like campus environment, placements, and other details, you can contact the alumni of the institute. The official website has an Alumni page. you can contact them through FB or Linkedin. They will be able to provide you with a clear picture. 

Hope that's helpful. All the best.
