hi,

see cutoff scores changes year to year and it depends on various factors like number of participants, questions difficulty level, seat matrix etc, iiits is one of the best institute after iits and nits, so at this score it has less chances for you to get iiits even for your category, now jee main april session exam is yet to held, and if  number of candidates increased this time, it will have effect on your current percentile, however you may also use careers360 college predictor tool to know about your probable colleges,
