I was going to receive a very bad evaluation even being told that I would fail that block of surgery. This resident made sure everyone on the team knew my weaknesses and started attacking them. Many of the comments used against me were taken way out of context (for example, a joke that became serious). This occurred after an attending in the previous block said I was great for surgery and had great interpersonal skills and above average knowledge and gave me a great-to-excellent evaluation. The Dean and course director recommended the best way to combat what I thought was an "unfair" evaluation would be to drop that block and repeat it later without taking the shelf exam.
Retrospectively, some of weaknesses cited were partially true and I have worked on them. My handling (getting defensive, etc.) of an already bad situation could have been better so that I could reverse an originally bad first impression. Luckily, the Dean told me because I didn't take the Shelf and dropped that block in the middle, none of it would stay on my transcript or Dean's letter, although I am still worried it will come back to haunt me somewhere. Also, I will only have to repeat that 1 month block of the rotation. So I think I got lucky, but who knows.
