Well at my school they still have to give comments in the eval, and I'm not trying to brag but my attending left very good comments and said I'm more competent that many of the residents he's worked with. But, I still got a pass on that rotation (and my shelf exam score was above the average). My school also has residents determine grades for some rotations and it is extremely abusive/malignant. What sucks about that is you are literally around a resident every minute of the day, and at the end of the rotation they all meet in a room and project your face on the wall and talk about you. Basically if you messed up even in the slightest way they will all hear about it and slam you on evals.
