Hello,

EWS Quota has been implemented this from this year and to sum up, its effect more or less is, if you are getting any seat in 25k rank as general then that seat will be available to you for 29k rank. I hope the expected impact of EWS quota has been cleared. Now continuing onto your question, your score of 91 percentile is not enough for you for securing seats in good IIITs due to their popularity and the demand of branches. 

My verdict will be that you may stand a chance in some new IIITs that too only in the special round and I highly recommend you to look for other state government colleges and good private colleges.

Thanks
