Course Grading System

8 out of 9 hands-on exercises count (worse exercise grade dropped)
1st partial exam = average of first best 4 exercise grades
2nd partial exam = average of last best 4 exercise grades
The average of these two is the same as adding up best 8 grades and dividing by 8. This result amounts to 75% of total grade (course letter grade score).

Final Exam amounts to 25 % of total grade.

After that, course letter grade is curved as shown below.

A (100-89%)
B (88-77%)
C (76-60%)
D (59-50%)
F (49-0%)

where

course letter grade score = (sum of best 8 exercise grades/8)*(0.75) + (final exam grade)*(0.25)
