Grading scale

Final Grade Formula

The final grade is the lower of:

1. The weighted average of Centering (10%), Corners (30%), Edges (30%), and Surface (30%), rounded up to nearest half point
2. The lowest individual subgrade plus 1

Off-center cards (worse than 65/35 on the front or the back) are graded without centering: the same rule applied to Corners, Edges and Surface only, and the grade is marked OC.
