Colleges in Ahmedabad

Your marks are fair but you would still need to score 99.4%+ in order to secure a call from IIM.

In my opinion, VIT Vellore is better for mechanical engineering than Nirma University because VIT provides good course curriculum and good mechanical faculty members also.

As per past records, it is very difficult to get admission.

For IIMB, percentile around 95-100 would be enough, but it depends on various other factors which changes every year.

Admission in IIMB depends on whether you have received a call. If you don't receive a call, you can't get admission in IIMB.

There is no specialisation as such. One can take electives as per choice and become a specialist in that field.

Hi Gaurav,
Before suggesting anything, it's important to know your graduation stream. If it's a non engineering steam, then you can secure admission in IIMs because with a very high CAT score and the marks of academic diversity, your low academic scores can be compensated.
However, if you are from engineering background, then you might face difficulties. In that case you should aim for other A league colleges like FMS, SIBM etc. which either don't consider past records or take minimal weightage for them.

Yes, CAT is accepted.

No, this college doesn't accept CAT score. Only CMAT.
The Minimum is 2 lakh and the maximum 10 lakh or more.
