hi sana,

For percentile of 74 your general rank should be more than 2.5 lakh and your obc rank should be 85k which makes your admission very hard in NITs, especially in good NITs like NIT Calicut. Even if you have OBC  quota, home state quota, female quota then also your admission is impossible in NIT Calicut . I am afraid to say that you cannot get any NIT with 74 percentile. Prepare for other state level entrance exam and try to get a seat in good state college.

I hope this answer will help.

All the best for the future!!
