Admissions to IIITs can vary slightly depending on the specific IIIT you are interested in. Generally, admission to IIITs is primarily through the JEE Main exam conducted by NTA.

While JEE is the primary route for the admission to IIITs, some IIITs might also have their own entrance exam or consider other national - level exams like the Graduate Aptitude Test in Engineering (GATE) for specific postgraduate programs.

It's essential to keep an eye on the official website of IIITs you're interested in for any updates or changes in their admission procedures. Additionally, regularly checking the official notifications and announcements from the NTA and JOSAA will ensure you have the most accurate and up-to-date information regarding the admission process.
