Hey!
According to your percentile, i.e. 74.8 in januray JEE MAIN, it would be highly unlikely for you to receive a seat at NIT or IIIT as cutoff for most of the colleges are 95+. However, you still have 2 months to prepare for the september JEE MAIN in which you should aim for a much better percentile. You can also aim for BITSAT, VIT exam and other competitive exams for engineering. To improve your performance, you should try to give more mock tests online and practice more.
