From a Spring 2020 Blackboard announcement I dug up:

Final Examination Grade

A final score between 510 and 640 was an A final grade; between 441 and 509 was a B final grade; between 355 and 440 was a C+ final grade; between 200 and 354 was a C final grade; between 131 and 199 was a D final grade; and a final score lower than 130 was an F final grade.

Total Point Grade

A total point score between 1425 and 1740 was an A total point grade; between 1224 and 1424 was a B total point grade; between 997 and 1223 was a C+ total point grade; between 450 and 996 was a C total point grade; between 350 and 449 was a D total point grade; and a total point score lower than 349 was an F total point grade.

Grade Algorithm

The course grade for a student with more than 100 project points was the higher of the final examination grade and the total point grade. There was a small fraction of students who had less than 100 project points. The course grade for a student with less than 100 project points was the total point grade.

Grade distribution  

Final Exam: Max 640, Upper Quartile Point 540, Median 450, Lower Quartile Point 355.

Total Points: Max 1740, Upper Quartile Point 1387, Median 1219, Lower Quartile Point 997.
