Hello

go to the website of the college and check in notices to see the schedule for the session and the commencement of classes.

The classes would start after the spot round of the counselling is over which is not yet announced by IPU.

You should also keep checking IPU website for more details which is: https://ipuadmissions.nic.in/publicinfo/Public/View.aspx?page=92.

Hope it helps.
