How to Submit Option Registration for CUSAT CAT 2026 BTech?

The option entry process is online and self-managed by the candidate. Each step must be completed before the deadline on June 22, 2026.

1. Visit the official portal at admissions.cusat.ac.in.
2. Log in using your CAT 2026 application number and password.
3. Open the BTech option registration module.
4. Check your final rank list and eligible branches.
5. Add branch and campus combinations in order of preference.
6. Rearrange the preferences if needed before locking.

Who Can Take Part in CUSAT CAT 2026 BTech Option Registration?

Only candidates who appeared in CUSAT CAT 2026 and figure in the final BTech rank list are eligible. The rank list is hosted on the same admissions portal for verification. Candidates outside the rank list cannot access the option registration module.

The university advises aspirants to cross-check their personal and category data on the portal. Any mismatch must be reported to the admission office before locking choices.

What Should Candidates Keep in Mind Before Locking Choices?

Branch order is the most important input in the seat allotment algorithm. The system allots the highest available preference based on rank and category. A branch left out of the list cannot be added once the window closes.

• List every branch and campus you are willing to join.
• Place the most preferred BTech branch at the top.
• Include backup branches lower in the list to avoid losing a seat.
• Verify the saved order before final submission.
