Hello priyanshu ,
Since you've not mentioned your quota/category , I am considering you belong to the general category .
So , considering a general category , it is a pretty good and well that you've scored such a good rank in pessat . I think that there are a good number of chances that you might get a seat in PES university in CSE branch .
As in last few years , the cutoff trend was around 1500 , so considering your 1440 rank in pessat , you might get your desired branch in PES University .
You can also check your admission chances in other colleges on the basis of your rank/percentile with the help of college predictor tool , here :
