hey mahasina

i doesnot know about pondicharry universitie's counselling process  but have a experience of counselling procedures . first check out if your name was in the first round but you visit on the second counselling.

also check whether you are satisfying other eligibility criterias also .

check out also  whether you have all the necessary documents with you .or there can be seats for special categories but chances are less for it .

this is very strange case as you scored very good .complaint onm the related authorities and ask them the reason for it .

also please repost this question as anyone from that university can answer you in more details.
