Hey Niharika,
Getting admission in IITs or NITs doesn’t depend only on your Class 12 percentage. The main criteria is your JEE performance. For IITs, you need to clear JEE Advanced after qualifying JEE Main. For NITs, admission is through JEE Main rank.
As per eligibility, you must score at least 75% in Class 12 (for General/OBC) or be in the top 20 percentile of your board. Since you got 74.8% overall, it’s slightly less than 75, but if your board’s top 20 percentile cutoff is lower, you may still be eligible. In that case, you can sit for JEE counseling.
So, your admission chance depends mainly on:
1. Your JEE Main/Advanced rank.
2. Whether your board percentile rule covers your marks.
So, If you clear these, yes, you can get into an IIT/NIT depending on your JEE score. Otherwise, you might need to consider other engineering colleges.
To appear in the JEE Mains exams, the students must have qualified Class 12 with Physics, Chemistry, and Mathematics as core subjects, and to appear in the JEE Advanced , the students must have attained 75% (for General/OBC) in Class 12.
As you are a student from the ICSE board , the percentage is calculated based on the best of 5 subjects, and based on this rule, your percentage is not up to 75%. Therefore, you are not eligible to appear in the JEE examination.
