i am looking forward to do complete my graduation level.. but, coz short of time shud i go 4 (complete in 1yr) from pariyar university??

It is preferable to do graduation by the conventional mode of education in the 3 year time specified for it. Any attempt for short-cut generally lead to disaster later in the career.

Single sitting courses are not recognised every where in India. Its better you do a full degree than go for a risk.
