It depends on your category and cutoff so cant give exact data. But i can tell you last years datas so you may have an idea

Last year’s cutoff for jee main

Gen-100

Obc -72 and st and sc about 50

…here in this batch most of the gen cat. Student,s marks are between 115–150. Have very good marks over 160 one or two about 200 but they are very few . So u can say 120–150 was a good score last year for mbm .and 130+ score was enough for cs and it branch .then for 120+ for ece ,eee,mech,electrical .and chemical and pi 115+.

2. So many students are here of sc and st cat.they marks are about 85+ .so for sc and st cat 85+ one could get branch.

For this year cant say exact but cutoff is

For gen 82 and for obc about 50 so if u r from gen cat 100 marks r enough for addmission .and for cs and it 120 is good score . Nd for obc 70–90 would be enough . St and sc student can get any branch upto 90
