Grades with this instructorGraded S/U only, so there is no average to report.
Grades with this instructorRaw is the average actually awarded. Predicted pulls it toward the course average, and then toward the department's, in proportion to how few grades there are, so twelve students cannot outvote six terms. A range is the share who got an A minus or better. D, F or W is the share who finished with a D or an F, or withdrew. There is no single average for this person: one figure over every course would be weighted by students, not by course, and the largest lecture would stand for all of them.
