How is pre-med GPA calculated?

Pre-med GPA is calculated by multiplying each graded course by its credit hours to create quality points, then averaging those points within the science category, the non-science category, and the total transcript. AMCAS and TMDSAS use BCPM, AACOMAS uses BCP, and TMDSAS removes plus and minus modifiers from grades.

What is the difference between AMCAS, AACOMAS, and TMDSAS GPA?

AMCAS and TMDSAS include math in the science GPA, so they use BCPM. AACOMAS excludes math from the science GPA and uses BCP. TMDSAS also strips plus and minus grades to the base letter, while AMCAS and AACOMAS keep them.

Do retakes count in pre-med GPA?

Yes. For AMCAS, AACOMAS, and TMDSAS planning, repeated attempts are generally counted rather than replaced. Even if your university transcript uses grade forgiveness, the centralized application service may still average both grades.

Do withdrawals or pass/fail courses count?

Regular withdrawals are usually excluded, while WF typically counts as F. Pass/fail and incomplete coursework are usually excluded until a standard letter grade is assigned.

What courses count as AO GPA?

AO GPA means all other coursework outside the service's science bucket. That often includes psychology, sociology, humanities, languages, arts, business, most engineering, environmental science, health sciences, and other non-BCPM or non-BCP categories.

What pre-med GPA is competitive?

Competitive pre-med applicants often aim for a total GPA above 3.6 and a science GPA above 3.5, though exact expectations vary by school list and service. Lower numbers can still be workable with stronger recent trends, a strong MCAT, and a realistic school strategy.

Is BCPM GPA the same as pre-med GPA?

Not exactly. BCPM GPA is only the science portion. Pre-med GPA planning usually looks at science GPA, AO GPA, and total GPA together because admissions reviewers see all of those numbers in the application system.

About This Pre-Med GPA Calculator

This pre-med GPA calculator is built for students applying to medical school through AMCAS, AACOMAS, and TMDSAS. It separates science GPA from AO and total GPA using the service distinctions that matter most, such as math inclusion in BCPM, math exclusion in AACOMAS BCP, and TMDSAS handling of plus and minus grades. It also supports quarter-hour conversion and repeated-attempt counting so you can estimate the standardized GPA medical school admissions teams will actually review.

How to Use the Pre-Med GPA Calculator

Follow these steps for an accurate Pre-Med GPA result

1Choose AMCAS, AACOMAS, or TMDSAS Mode

Start by selecting the application service you want to mirror. AMCAS and TMDSAS use BCPM, while AACOMAS uses BCP and excludes math from the science GPA.

2Enter Every Graded Course Attempt

Add each graded college course you want reviewed. This allows you to estimate the science, AO, and total GPA numbers medical school application services will standardize from your transcript.

3Classify Biology, Chemistry, Physics, Math, and AO

Assign each course to Biology, Chemistry, Physics, Mathematics, or AO. The calculator uses that classification to split science coursework from all other coursework.

4Convert Quarter Hours Automatically

If a course was taken on a quarter system, switch the row to Quarter units. The calculator converts quarter hours into semester hours using the standard 0.667 factor.

5Keep Repeated Attempts in the Calculation

Pre-med service-style calculations generally count both the original and repeated attempt instead of replacing the earlier grade. That can materially change your science GPA estimate.

6Compare Science, AO, and Total GPA

Use the summary cards to compare science GPA, AO GPA, and overall GPA so you can see whether your application is being driven more by your core sciences or by non-science coursework.

Pre-Med GPA Types Explained

Science GPA

In AMCAS and TMDSAS mode this is BCPM GPA, which includes Biology, Chemistry, Physics, and Mathematics. In AACOMAS mode it becomes BCP GPA and excludes math.

AO GPA

AO means all other coursework outside the science bucket used by the selected service. This is the main non-science GPA reference in pre-med planning.

Total GPA

Total GPA includes every graded course you enter. Admissions committees see this alongside science and non-science breakdowns, not as a replacement for them.

Service Differences

AMCAS and TMDSAS include math in science GPA, AACOMAS does not, and TMDSAS strips plus and minus grades. Those differences can change both your science GPA and your total GPA.

How Pre-Med GPA Is Calculated

1The Formula

Science GPA = Σ (Science Credits × Grade Points)

Σ Science Credits

The same quality-point method is also used for AO GPA and total GPA. Quarter-hour classes are converted into semester hours first, and repeated attempts are generally kept in the calculation instead of replaced.

2Key Pre-Med GPA Rules

•AMCAS and TMDSAS use BCPM, which includes math in science GPA.
•AACOMAS uses BCP, which excludes math from science GPA.
•TMDSAS removes plus and minus modifiers before calculating GPA.
•Repeated courses still count in AMCAS, AACOMAS, and TMDSAS planning.
•WF usually counts as F, while regular W and pass/fail are usually excluded.
•All institutions are usually combined in centralized application GPA review.
