This semester is the first time I've ever had a teacher that did a test review like that (and it's my last semester), and I personally hate the subjective push. Before this semester, it was always by statistical analysis, and they used an objective ruling. So there were questions that stood and ones that didn't, and it was the end of the story, regardless of the individual students that wanted a higher grade.
Adding the ability for students to challenge some on their own grounds had made it really murky and biased, and I hate it, because I, too, work hard for passing scores, and hate the fact that many people have been pushed through that wouldn't have passed otherwise.
So glad that I'm done after this semester, can't lie.
