I had a class where a 40% was an A. It was tough to get 40% in that class. What a good %age is can be dependent on how hard the work was. It's not trivial to make all the things being tested such that you can easily see where people need help AND you simultaneously get the traditional >90% = A. Now, I think I'd rather the teacher knew where I hadn't grasped enough. When you're doing it though, trying hard and only getting half the stuff right can be frustrating.
