With a CUSAT CAT rank of 16,689, you have a fair chance of getting admission into several engineering branches. At the main campus in Thrikkakara, you may get branches like Civil, Mechanical, Electronics and Instrumentation, or Safety and Fire Engineering, especially in the later rounds. The more competitive branches like CSE or ECE at the main campus may be harder, but still possible depending on the category and seat availability.

At the CUCEK (Kuttanad campus), your chances are better for branches like CSE, IT, and ECE, since the closing ranks are generally higher there. So yes, admission is quite possible—focus on filling in your choices carefully during counselling to maximize your chances.
