The behaviour of faculty towards students totally depends on the college.
The staff sometimes don't behave properly to the pmsss students while in some colleges pmsss students are treated equally with other students.
There are few cases where students were not treated equally and were charged extra fees as compared to other students.
You have to be very careful while your choice filling as it will decide which college will be allotted to you.
Please do proper research before filling that college so that you don't regret it later.
