Hey. Sorry for your CK! These tests are so unpredictable sometimes. Maybe it was a time management issue? I felt time management was really tough on CK. You are still good to apply for the match this year. Get back to study and ace this thing. If your UWSA was 232, you should be fine next time, but I would recommend you take some nbme to be on the safe side...
Thanks again for giving hope to all of us who felt so doomed after CS!
Best of luck!
