A 93 - 96 4.0

A- 90 - 92 3.6

B+ 87 - 89 3.3

B 83 - 86 3.0

B- 80 - 82 2.6

C+ 77 - 79 2.3

C 76 - 78 2.0

C- 70 - 72 1.6

D+ 67 - 69 1.3

D 65 - 66 1.0

F 0 - 64 0.0

If you get the GPA of the 4 marking periods and multiply them by .2 (20%) and add on the two exams multiplied by .1 (10%) you will get a GPA which you can then convert to the final letter grade.
