Grade scales
I keep numerical scores throughout the semester and convert to letter
grades only after calculating the average grade for the entire course.
As a result, the average for 2 A's and a B is often B, and conversely
the average of 2 B's and 1 A may well be an A. The scale for
each exam will be announced here after the exam is graded.
Use your numerical exam grades to get your average grade and compare
with the table here.
