Hello Dankorir,
I totally get how stressful this must be—it sounds like a frustrating situation.
If your CAS is stuck at 61%, it might be worth emailing or calling the admissions or international team at Sunderland directly instead of relying on your agent. Sometimes agents can slow things down, even something similar happened to me as well when I was in process with Coventry university but then I contacted Coventry University and it was all sorted in a very less time frame.. Be polite but firm when asking for an update, and mention your payment date and CAS submission to show that you’ve done your part.
Transferring to another campus could be an option if their enrollment deadline gives you enough time, but you’d need to check with the university if they allow it. Be sure to explain your situation and ask if transferring might speed up the CAS process.
Hope this helps a bit—fingers crossed they sort it out for you quickly! Let us know how it goes!
Thanks & Regards
