Although students may be told that they won't get a hostel in earlier stages after waiting for a few days the students in the Chandigarh quota can get a hostel in PEC. But there is some process that needs to be completed in order to get a hostel in PEC.
You have to submit an application to the hostel warden and you have to mention your reason clearly, why do you need a hostel after being from Chandigarh as they don't provide hostel facilities to the students belonging from Tricity (Mohali, Chandigarh & Panchkula).
But the first preference is always given to the students who are taking admission through all India quota and they are allotted the hostel rooms first. But after a few weeks from their allotment of hostel rooms, the students in the Chandigarh quota who have applied and submitted an application will get the hostel rooms.
