MBA/PGDM

First let me clear one thing for you. JSS DENTAL COLLEGE Is a college of medicine which deals with dental course like Bds Mds 

so if you are planning to pursue MBA I don't think it's good idea because they don't offer such courses. 

So You have to pursue your MBA From other colleges.  And for cost you can make the list of colleges and accordingly you can visit their official website for confirmation.

The choice between an MBA and a PGDM course totally depends on your career goals, personal preferences, and the reputation of the institution offering the course. MBA is a degree course is recognised globally. MBA has a more theoretical approach and covers selective subjects in management. On the other hand, PGDM (Post Graduate Diploma in Management), is a Diploma course offered by autonomous institutions approved by the All India Council for Technical Education (AICTE). The Programme content of the PGDM primarily focuses on practical skills and industry-specific knowledge.

First of all  there is no such course offered by this university as it is medical college in which dental course is offered so to keep in mind that you can't pursue MBA in this university. 

And if you want to pursue I would suggest you to research some other universities accordingly to your preferences.

For admission to the IIM and top MBA colleges, a CAT score of 90 percentile is considered good. Meanwhile, for tier-2 and tier-3 MBA colleges, a 75-90 percentile in CAT is considered good. But many colleges also offer admissions at 50-70 percentile. 

And after these criteria, students get selected according to graduation scores in some colleges.

Some of the colleges may require at least a 6 to 7 CGPA in graduation.

As per the eligibility criteria of SRMU Lucknow for the MBA course. Candidate must have passed Graduation or equivalent system in any discipline from any recognized University or AICTE recognized Institute/College with minimum aggregate marks of 50% or CGPA of 5.5 for Gen/OBC category and 45% marks or CGPA of 5.0 for SC/ST Category. Shri Ramswaroop Memorial University (SRMU) in Lucknow is known for its good placements and quality education.

First of all, this is a dental college. The only courses offered by this university is BDS and MDS, so if you are planning to pursue MBA in this college then unfortunately it's not possible. 

You can apply to other universities for your course and if you have CAT results then I think it will be more beneficial to you.
