hello aspirant,

As of now its tough to say because the analysis and also cutoffs change every year due to many factors like total students appearing for exam,difficulty level of paper etc.however based on previous year analysis there are some expected cutoffs.note that this year the cutoff will be released after all the jeemain sessions will be held i.e after may.for OBC NCL the last year cutoff for qualifying jeemains was 72.8887969 .so the expected cutoff percentile  for an obc candidate would be from 70-75 percentile.note that is the qulaifying percentile cutoff and not the admission cutoff.for more information refer to: https://engineering.careers360.com/articles/jee-main-cutoff

hope this helps,

thankyou.
