Hi Jack,

There is no particular way to predict whether or not you will be able to secure admissions, however, based off of last years cut-offs it seems unlikely for you to be able to secure a seat in any college through the CUSAT CAT exam unless you belong to any particular reserved category.

I will attach the link to the previous year's cut-offs below, you can match your rank against previous years rank by your category and see if you are eligible for any course through the counseling.
