Will I get admission in CUSAT with 6615 rank in spot round?

The closing ranks for CUSAT CAT 2022 for general category in different branches in B.Tech are as follows-

As you can see, for a general category candidate, the closing ranks did not go beyond 3000 in the previous year. However, for an SC/ST candidate, the closing ranks are more relaxed. Also, if you are from some other state, 50% seats are reserved for Keralite students.

During CUSAT spot allotment, you can get the seats that are left or not filled up. These seats are filled rank-wise. Speaking statistically, a lot of students who are above you rank-wise will show up during the spot allotment. So, your chances depend upon the number of candidates above you who show up on that day.
