## Default answer

Example with the default inputs (Science course 1 grade A-, Science course 1 credits 4, Science course 2 grade B+, Science course 2 credits 4, Science course 3 grade B, Science course 3 credits 4, Science course 4 grade A, Science course 4 credits 3, Science course 5 grade Not counted, Science course 6 grade Not counted, Science course 7 grade Not counted, Science course 8 grade Not counted): Your science GPA is 3.47 over 15 credits.

| priorCredits | Science credits so far | The science credit hours that GPA covers. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| gpa | Your science GPA | The grade points of these science courses divided by their credits, on the 4.0 scale. |
| credits | Science credits | The credits of the courses that count. |
| points | Grade points | The sum of grade points × credits over the courses. |
| cumulative | Overall science GPA | The science GPA over the earlier courses and these courses together. |
| totalCredits | Total science credits | Credits so far plus the credits of these courses. |

## Method

Science GPA = Σ(grade points × credits) ÷ Σ(credits) over biology, chemistry, physics and math courses; overall = (GPA so far × credits so far + Σ(grade points × credits)) ÷ (credits so far + Σ(credits)).

## Assumptions

- Enter only science courses. The groups are the AMCAS BCPM groups: biology, chemistry, physics and math.
- Grade points are on the 4.0 scale: A+ and 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 (or E) 0.0.
- This is an estimate of a science GPA. An application service works out its own figure from your transcripts.
- Courses marked Not counted are left out of both the grade points and the credits; an F counts with 0 points.

## Worked examples

1. grade1 = a-minus, credits1 = 4, grade2 = b-plus, credits2 = 4, grade3 = b, credits3 = 4, grade4 = a, credits4 = 3 gives gpa = 3.47, credits = 15, points = 52.

2. grade1 = a, credits1 = 3, grade2 = b, credits2 = 1.5, grade3 = c-plus, credits3 = 4, grade4 = none gives gpa = 3.02, credits = 8.5, points = 25.7.

3. grade1 = a-minus, credits1 = 4, grade2 = b-plus, credits2 = 4, grade3 = b, credits3 = 4, grade4 = a, credits4 = 3, priorGpa = 3.2, priorCredits = 30 gives gpa = 3.47, cumulative = 3.29, totalCredits = 45.

## FAQ

### How do I calculate my science GPA?

Take only your science courses. Multiply each grade’s points by the credits, add them up, and divide by the science credits. A- in 4 credits, B+ in 4, B in 4 and A in 3 give (14.8 + 13.2 + 12 + 12) ÷ 15 = 52 ÷ 15 = 3.47.

### Which courses count toward a science GPA?

For the AMCAS medical school application, the BCPM GPA covers biology, chemistry, physics and math. That includes courses such as anatomy, genetics, microbiology, physiology, biochemistry, organic chemistry, astronomy, calculus and statistics.

### Does a natural science course count?

Not in the BCPM GPA. The AMCAS guide says that natural and physical sciences courses are not included in it.

### How is a course classified if it covers two subjects?

AMCAS says to classify a course by its primary content. For an interdisciplinary course, check the course description on your school’s website or ask your prehealth advisor.

### Will my result match my AMCAS GPA?

It may differ a little. AMCAS works out its own GPAs from your transcripts, and this page uses one common 4.0 scale. Treat the result as an estimate.

### I have more than 8 science courses. What do I do?

Open "Add earlier science courses" and enter your science GPA so far with the credits it covers. Then enter your newest courses in the rows.
