MBA/PGDM

Yes,
For admission in top rated management institute in country, you need to crack CAT, XAT, and GMAT Exam.
Most of the good B-School take admission through entrance exams score.

You will need to obtain a bachelors degree of minimum 3 years duration with at least 50% marks (45% for SC/ST candidates) from a recognized university in Pharmacy, Medicine (MBBS), BDS, Biotechnology, BAMS, BHMS, Science and Management with a valid score of entrance exams like MAT/ GPAT /CAT /CMAT /ATMA/ GMAT/ XAT/ IIHMR -U MAT.

Go for MCA as it will help you in flourishing your career in IT sector.

Some of the jobs that students with an MBA degree in HR Management can take include Compensation Manger, Manager of Employee Relations, HR Generalist, Technical Recruiter, Director of Staff, Placement Manager, Training and Relations Manager, Organizational Consultant and more. Good luck.

You can take any degree, because degree makes no difference. If you want to do MBA, you can do with any graduation course you have done. Good luck.

I would suggest you not do a dual degree. You can do MBA after graduation. Doing MBA after B.Sc is not difficult. MBA is a practical oriented course and Science student are able to do it well. Initially business students have about 10 percent advantage but at the end everyone is at the same level. After doing MBA and securing a good placement no one will ask your graduate degree, everyone will only be interested in your PG degree. Good luck.

It doesn't matter, if you have gap between educations during the time of admission. Score high and take admission. It matters during the time of placement. Fact is that you have to explain the valid reasons of 2 year Gap.

Chances are less, because you have a bit low score in your class 12th, and even in your graduation. Now, it depends upon your competitive exams, if you manage to get good score. Definitely, you can get admission for PGDM course.

No, there is no change in the number of seats. The seats are same as it was previously.
If you heard somewhere about the reduction in number of seats of PGDM, it is not true.
