Calculating your class GPA

Each letter grade is assigned a number on a four point scale.

A  =   4.0

A- =   3.7

B+ =  3.3

B   =  3.0

B-  = 2.7

C+ =  2.3

C   =   2.0

C-  =  1.7

D+ = 1.3

D   = 1.0

D-  = 0.7

F   =  0

Average the numerical points for all of your grades by adding them and dividing by the number of grades. Here is a list of grades to average:

A   = 4.0

C   = 3.0

B+ = 3.3

C+ = 2.3

B-  = 2.7

A-  = 3.7

B   = 3.0

          22 / 7 = 3.14  or slightly higher than a “B”

If your grades are weighted, say the 7 grades above are worth 80% of your grade and the final exam is worth 20%, multiply the total (3.14) times 8 (for 80%) which equals 25.12.

Then multiply the grade on your final by 2 (for 20%). If you got a B- on the final that would be 2.7 x 2 = 5.4

Add these numbers and divide by ten.

25.12 + 5.4 = 30.53 / 10 = 3.1  or a “B” for a final grade

If you had aced the final:

25.12 + 8 = 33.18 / 10 = 3.3 or a B+

So doing really well on 20% of your grade can make a difference!
