I have completed b.tech in 2014 from ptu. I am saying about demerit of ptu.
This university has no rank in India . Because this is only university of india that gives a 4 yrs chance to complete b.tech after 4th yrs.
Due to this every student of this university does not serious with study . and due to some rule like back semester during backlog of subject is not here. due to all region campus placement does not possible because evry company know what is the status of this university.
So all company does not want to visit in university. many college under this university show on thier site a fake placement. There is no carrier in this university and it is totally waste of time for student.
