Grading "on the curve"; hit the average grade and you get a C (or somewhat higher for "advanced" classes), even if that's only 50%. Standard procedure for most college/universities, but quite a shock to all the "smart" people used to getting 90% without having to exert much effort. And as you say, it can be frustrating if the low grades are because the teacher isn't getting the material across (at my U, it tended to be more due to material on exams that was never covered in class, or just exams that were too long to do in the time allotted.) In any case, a class where everyone gets 80%+ all the time just isn't hard enough to weed out the pre-meds that shouldn't be there (which is, perhaps sadly, sometimes one of the goals of intro-level science classes in university.) (this doesn't mean that your teacher is better than you think, it just means that you can't necessarily tell from the exam grades.)
