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!
