Yes, as you have itself declared that you got the college in second round. I would ask you to try for C. E IIMP for the remaining round you may get in to it.

Yes. CMAT is necessary to apply for admission in MBA programme.

Fees is equal for everyone. If IMS has allotted you the admission seat they would also given you the fee structure letter or brochure on which how much you have to pay and when and through which mode will be written.

Sorry dear but since your rank is way below so I don't thil you will get admission in ims, because they allot seats on rank basis.

For admission in any management colleges in India, you need to appear for CMAT or CAT. So getting a good college that is UGC approved, you need to give a eligibility exam. You need to give CAT, CMAT or ATMA for getting into eligibility. For direct/paid admissions also, you need to have the eligibility criteria cleared.
Thank you.

Yes, you are eligible for admission in PGDM.

Hello,
It depends upon the college in which you are taking your admission.
