NL Dalmia Institute of Management Studies and Research

CMAT score of 71% is too low.
But, you can try for PGDM and do extremely well in the GDPI rounds to stand a chance.

For PGDM marketing, it is around 5-6 lakhs.

You should try again next year because 54 percentile is too low for Dalmia. But you can clarify about the 49% aggregate from the institute.

Your score is good for both the colleges. I don't have any idea about ACAP. Just check the ACAP side.

In my opinion you will stand a better chance by applying next year if you plan to give the exam again. Else, just go for your profile evaluation for Global MBA programme offered by N.L Dalmia if you have a good past record and want to study with top international MBA institutions.

10% of weightage during your entire profile evaluation is given to your past academic record. So yes, these marks will matter but more importance is given to your entrance exam marks and GD-PI.
The last date for application is April 20, 2018. I think you should go ahead and apply. All the best.

78 percentile in CAT is much better than 78 percentile in most other entrance exams. Certain people in N. L. Dalmia have secured admission only due to a great profile and good performance in GD/PI with percentile near about this (I myself being one of them). The last date for application is April 20, 2018. I think you should go ahead and apply.
All the best.
