hello aspirant,

The cutoff for jeemain will be released after the may session.so 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.  but based on previous year analysis there are some expected cutoffs and are as follows:

GEN-90-95

GEN EWS-70-75

OBC-NCL-70-75

SC-50-55

ST-40-45

PWD-1-2.

but the cutoffs will be somewhere close to the above mentioned cutoffs.based on this you are eligible to give your jee advanced exam.now 74.24 percentile would fetch you a rank around  263525-296240 and category rank around around 17k-20k.with your rank you will have nearly no chances to fetch in nits and iiits.in iiits also the last year cutoffs closing ranks were near to 6k for your category.you have rank more than that.nevertheless you have work hard and improve your score in the upcoming jee mains and score better  to 95-98+ perentile for your category to fetch seat in good branches and good nits.for more information refer to:

hope this helps,

thankyou.
