You are graded? The mentors aren't told that though, some do some grade on stage you're at. I was talking to another stude recently who said her last mentor told her when she did a grading with a uni tutor she found out she'd been undermarking quite a bit. I imagine other overmark and I also imagine another tutor would have told the same mentor she was overmarking. It is so subjective it's unfair in many ways.
