How to Compute your Grade-Point Average

Marlboro College does not routinely compute your grade-point average (GPA). Other institutions, however, may require you to translate your Marlboro grades into a GPA. This form is designed to help you do that.

Numerical Equivalent of Grades:

A A- B+ B B- C+ C C- D+ D D- F
4.0 3.67 3.33 3 2.67 2.33 2 1.67 1.33 1.0 0.67 0

Do not include progress grades (S,U) or pass/fail (P/F) grades. Do the following for courses completed in your Freshman, Sophomore, and Junior years at Marlboro.

  1. If you received an A in a 4-credit course, multiply 4.0 (the numerical equivalent, quality points, of an A) by 4 (the number of credits) to get 16.0 (quality points).
  2. Do this for every course you took, keeping a running total of your credits and quality points.
  3. Divide the grand total of your quality points by the grand total of your credits.

For example:

John Doe took 4 courses at Marlboro. His grades were:

Literature: 4 credits of B History: 4 credits of A
Physics: 3 credits of C Calculus: 3 credits of B+
Course Credits x Numerical Equivalent of Grade = Quality Points
Literature 4 3.0 12.0
Physics 3 2.0 6.0
History 4 4.0 16.0
Calculus 3 3.33 9.99
Totals 14 12.33 43.99

John would divide 43.99 (grand total of his quality points) by 14 (grand total of his credits) to get 3.13. He would round this figure to 3.1 for his GPA.


If you have completed your Plan of Concentration, follow the above procedure for your freshman, sophomore, and junior years, as well as for any senior year courses outside of Plan (i.e., courses listed under "outside plan of concentration" or on older records, courses not denoted by double asterisks). To find the number of quality points you earned on Plan, multiply the number of your senior year credits on plan by the quality points corresponding to your final Plan grade. Do this whether you received a cumulative grade (denoted by an *) or standard A-F grades during your senior year.
Both types of senior grades are progress grades only and are superseded by the final Plan grade.
For example, let's say that you earned 30 credits on Plan in your senior year and your final Plan grade was B+. Multiply 30 x 3.33. Add the result (99.90) to the total of all other quality points. Then divide that total by the total number of credits (both on and off Plan) you earned at Marlboro.
