CUSAT exams are of 750 marks also the CUSAT CAT exam is hard to give. Here’s what I got to know from some of my friends studying at CUSAT.
CSE is the most sought out branch in CUSAT in both of the campuses, therefore a 400 waitlist opportunity will take a long time to come to you. Even if it does, the CSE seats would be filled for both campuses in the general category. With a reservation, you may still have luck finding yourself a chance to get the CSE seats in spite of the waiting list.
