Hey Adina, TS PGECET is a state level examination.TS PGECET 2019 counselling will be started from  july 2019 as per the updates . This whole process consists of certificate verification followed by choice filling and seat allotment.  I would recommend you to go to a counsillor because even if you are not able to get admission in a college of your choice the counsillors can help you go through it as they have more knowledge about the last rounds the domicile structure and the spot rounds. Many students cant get admitted because they dont know about the spot round. 

Best wishes.

He adina,hope you're doing well,TSPGECET counselling dates are not yet confirmed so hold on for the update at official website
