1. University of Cincinnati
2. Honors/High Pass/Pass/Fail
3. yes
4. Each class has their own scale. Some are curved, some are not. And then some are semi-curved. Surgery, for example, has a set number of people who will be Honors, High Pass, etc. in each group. So the top 5 get Honors, next 10 get High Pass, etc. But if you don't perform so many SDs above the mean on the Shelf, then you are ineligible for Honors, and the highest you can possibly get is High Pass.
Some of them are really complicated, and some students really immerse themselves into understanding the intricacies of these byzantine grading schemes. I prefer to spend my time on more productive things, such as studying, working, and enjoying my free time. You get what you get, and knowing the complicated formula behind your grade isn't going to change that, IMO.
