The cutoffs for CSE in BITS Goa/Hyderabad and Pilani campus change every year very abruptly.But going by the cutoffs closely for past according to my point of view a score of 380 and above will make your chances high for getting CSE in Pilani campus.A score of 360–380 would be good for the other two campuses.But nothing can be said with surity as cutoffs are full of surprises.
