Dear Sarang Rajurkar

Phase 1 admission process is same for all students irrespective of reservations.Those who have cleared the cutoff are eligible for next round i.e. interview.

You have received pretty good score in CAT which will result in your qualification to phase 1. Here you need to crack interview for further process.As IIM conducts a very different method for recruitment. Based upon your GD and PI round a cut off is declared. As IIM has not officially declared its cutoff but tentatively the cutoff for open/general category is 90.Hence reserved categories will have less cutoff then general ones.

Therefore I think that you have marks up to  your cutoff which will lead you for entering in Phase 1 step of IIM

All The Best
