hello aspirant

well for obc students there is 27%reservation .well you can get into NIT OT IIIT under reservation of seats for girls and you need to see that the preference given to state .that is 50% seats are reserved for home state quota students and 50% for other non locals .using all this criteria you can make an assumption

hello,

Last year cutoff for JEE Mains OBC Category was 74.3166557 Percentile.

Yes, with 89.6 percentile with OBC Female Quota you have a good probability of getting NITs and IIITs. You can easily get all good branches like CSE, ECE in lower NITs like NIT Manipur, NIT Nagaland etc and Core branches in top NITs like NIT Trichy, NIT Warangal etc. You can easily get into the top IIITs also with OBC Female Quota
