Hello

I am extremely sorry to tell you dear but you are not eligible for JEE advanced exam.

This is because

To be eligible for JEE advanced examination in OBC category student like you need at least 75% marks in class 12th board examination as

Eligibility criteria says that to be eligible for jee advanced( for iits) one needs at least  75% marks in aggregate in class 12 if belong to general or obc category or at least  65% marks if belongs to SC/ST or  must be in the top 20 percentile in  class 12 examination.

So ,  with 74.4 percent you fail to fulfill the eligibility criteria and so you cannot appear in JEE advanced examination

Thank you
