My overall CAT percentile is 96.5 but I got 80 percentile in QA, Do I have a chance at getting a call from any IIM?

Yes of course new IIM calls chances are very high

Does NMAT has negative marking?

No. It has an adaptive marking scheme. i.e. the higher your accuracy, the more difficult questions you get. Easier questions fetch you less marks as compared to difficult ones.

My NMAT score is 210. VA-75 DILR-72 & QA-63. And date of exam is 08/12/2021. Do I have any chance of getting call from XIMB Bhubaneswar or KJ Somaiya ? Please Answer.

I think both KJ and XIMB (HRM) have similar cutoffs. It was ~225 last year. KJ will only consider the Main attempt, but if you really wanna try for XIMB HR then maybe give another attempt.

My overall Percentile as per Cracku percentile predictor is 95.58 but my verbal scaled percentile is 70.25 percentile. Do I have any chance of getting an IIM Call?

No But hope that va crosses 75 coz new iims are expected to have lower sectional cutoffs this time

Do we need to cross 90 percentile in sectional to get a call from IIMs?

Hi All IIM's have their individual sectional cut off's some have it 80 80 80 , some have it at 70 70 70 , I would advice you to check on their website.
