MAT

You should not believe blindly on college rankings. I would suggest you to apply for:
1. Christ University – Bangalore.
2. Alliance University – Bangalore.
3. Balaji Institutes – Pune.
4. XIME – Bangalore.
5. XIMR – Mumbai.
6. ITM - Mumbai.
These are some of the best colleges, which accept MAT scores and where you will stand a chance for a GD/PI call.

IIMs do not accept MAT scores for their admission process. IIMs conduct CAT. CAT scores are used by IIMs for selecting students for PI and WAT .

You can try for Balaji Institutes – Pune, Christ University – Bangalore, Alliance University – Bangalore, PUMBA – Pune, ITM – Mumbai, BIMTECH – Noida, XIME - Bangalore and XIMR - Mumbai.

You can opt for Christ University or XIME - Bangalore.

You can try for XIME and you may get a call from them. You can also try for ITM – Mumbai, Christ University – Bangalore, Alliance University - Bangalore and Balaji Institutes - Pune.

You can try for Balaji Institutes – Pune, MIT – Pune, FLAME – Pune, ITM – Mumbai, Christ - Bangalore and Alliance University - Bangalore.

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.
