Hello Aspirant,

According to your score 89.29 percentile in JEE mains, your general category rank will be around 92303-169542 . And your SC rank will be around 3,000 .

It is little difficult to get CSE branch in top NITs because getting a seat will depend on varies factors such as number of students applied for the same branch, performance of the students, category of the students, home state etc. Need 7,000 rank to get admission in any decent NITs. But with this rank you might get chance in top NITs if seats are available but you can not get top branches.
