With a JEE Main percentile of 91.23 in the general category you have a moderate chance of getting an admission in National Institutes of Technology and some Indian Institutes of Information Technology specifically for branches other than the most competitive ones like Computer Science Engineering or Electronics and Communication Engineering. Your percentile indicates that you may be eligible for various branches such as Mechanical, Civil, Electrical, and others in NITs.

Also, you can consider IIITs that offer slightly lower cutoffs for branches like Mechanical Engineering or Electronics and Communication Engineering. You can  thoroughly research the previous year cutoffs and consider participating in counseling through JoSAA and CSAB  to explore the best options available based on your preferences and eligibility.
