Your science GPA is comprised of grades in medical school prerequisite classes like biology, chemistry, physics, and math.
It is more important because it is a better indicator of how well a student will be able to handle the science classes at medical school.
A science GPA around 3.3-3.4 is Very Good, one between 3.5-3.7 is usually Excellent and one above 3.8 is generally Superior.
Formula to calculate science GPA.
To calculate your science GPA;
- Make a list of all science courses you took.
- Convert your grades into their numerical equivalent. 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 and F = 0.
- Determine the number of credit hours for each of your science courses.
- Multiply each science course’s numerical grade equivalent by its respective number of credit hours.
- Add up all the results and then divide their sum by the total number of semester hours for all of your science courses.
Example:
Suppose in a semester a student took 3 science courses that is; Chemistry, Anatomy and Math. If in Chemistry she had an A- with 2 credit hours, in Anatomy B+ with 3 credit hours and in Math A with 4 credit hours, calculate the student’s science GPA.
Chemistry A- = 3.7 ; Anatomy B+ = 3.3 ; Math A = 4.0
Total semester hours are 9.

Therefore, the student’s GPA is 3.7.
