Hi aspirant,

Actually, you should specify which NIT or IIIT is this question for. According to the official website of NIT Trichy, regular classes for both UG and PG will start from 22nd July. So, you can expect all the NITs to start from that date only. IIITs also start around the same date.

All the best

Well joining dates for different nit and iiit are different. As you know that IIIt and NIT are autonomous institute and they decide their own schedule. So it depends on the college which you are joining. 

If you better visit your college website , their you will find the academic program.

All the best.

Dear Reader,

It varies from college to college. If you got an allotment in any of the IIT then they will either communicate to you through mails or through the official announcements on their website. So just stay updated and visit their website regularly. Also check your mails regularly. Incase nothing works then keep in touch with their admission cell
