The Department of Pre-University Education (DPUE) has put up the calendar of events for Pre-University (PU) courses.
According to the notification, the II PU classes will begin on June 1 and I PU classes on June 15.
The last date of issuing application forms by colleges is May 18 and they will have to stop accepting filled-in forms on May 23.
The notification also says that colleges will have to put up details of their recognition, reservation, and roster on a flex board by Thursday.
Colleges have been warned of disciplinary action if they failed to adhere to the calendar of events.
But it makes no mention of action taken against many colleges, which have already flouted the calendar and started admissions before the SSLC results were announced.
