Congratulations on your great performance!!

With this percentile, you will definitely get calls from all the ultra new IIMs like IIM Sambalpur, IIM Nagpur etc. and most of the new IIMs like IIM Kashipur, IIM Trichy, IIM Rohtak etc.

You also have a wonderful academics plus you are a non-engineer which adds to your aggregate score so you might even get calls from old IIMs like IIM Indore because it gives even more weightage to academic records than CAT percentile and IIM Shillong.

So, I highly recommend you to sit for the procedure as you will be getting IIMs shortlists pretty soon and then there will be the second round of WSAT and interview in the month of Jan-March.

But if you are really looking for IIM A, B, C, L and K then you can give CAT exam again next year and with your 99+ percentile and awesome academic records you can expect calls from all IIMs.

Trust in yourself, analyse and then make a decision wisely.

All the best!!
