Hello student,

If you haven't taken the JEE (Joint Entrance Examination) but have appeared for the IISER Aptitude Test, you won't be eligible for admission to IITs (Indian Institutes of Technology) or NITs (National Institutes of Technology) because these institutions primarily admit students based on their JEE Main and JEE Advanced scores.

However, your IISER Aptitude Test score can be used for admission to IISERs (Indian Institutes of Science Education and Research), which are prestigious institutions focused on science education and research. If you're specifically looking to join IIT or NIT, you would need to take the JEE exams in the future.

I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.

Thank you and wishing you all the best for your bright future.
