No, waiver of fee on the basis of percentile is not applicable. Yes, there may be some chances if you belong from reserved category (maybe).
Admission in IP will be made on the basis of rank obtained in CET i.e common entrance test.

Yes it is very much important to take these exams. Actually when you prepare for these exams you get to know and analyse things in a better way or it will be accurate to say in a logical way. That is very much required in a corporate world. So these exams test your reasoning and analysis capacity. So it is better you secure your admission through these exams. It will benefit you in long run.
Best wishes!!!

MAT December is not accepted for admission into SIMSREE. February MAT is accepted, the cutoff for which is 99.96 percentile.

You need to be score more than 80 percentile. By January end you will get to know officially how much exactly IBS is taking admission on MAT. But after that still you have clear GD/PI.

IIM Indore does not consider MAT scores for PGP admissions.
