# What are some interesting grading/curving systems you have seen for a course? [closed]

It seems like every math course has something unique in how things are graded.

1) What are some interesting grading systems you have seen/used? (include curving types, etc.)

2) What are some pros and cons to this particular system?

3) Would you use it again if you have used it yourself?

I recall $10\sqrt x$ at the Hebrew University.
