AADSAS GPA Calculator
Calculate your AADSAS GPA for dental school applications — including the critical BCP GPA (Biology, Chemistry, Physics), Science GPA, Non-Science GPA, and Overall GPA. Handles the all-attempts repeat policy, WF grades, AP credits, and quarter-to-semester conversion — all on the ADEA AADSAS 4.0 scale.
What is the AADSAS GPA?
The ADEA AADSAS GPA is one of the most comprehensive academic metrics in health professions admissions. Rather than accepting the GPA printed on your university transcript, AADSAS (the Associated American Dental Schools Application Service) independently recalculates your academic performance from every transcript you have ever generated — using a uniform 4.0 scale and a strict policy that requires all attempts, including failed courses, to be reported.
What distinguishes AADSAS from most other application systems is that it does not produce a single GPA — it produces four separate sub-GPAs. Each one measures a different dimension of your academic record: the BCP GPA isolates your performance in the three foundation sciences (Biology, Chemistry, Physics); the Science GPA broadens that to include Math and other science disciplines; the Non-Science GPA covers humanities, social sciences, and business; and the Overall GPA represents everything combined. Dental schools use all four numbers together to build a complete picture of your academic readiness.
Because AADSAS ignores your university's grade forgiveness policy and applies its own quarter-credit conversion, your AADSAS GPA may be meaningfully different from the GPA on your diploma — sometimes significantly lower if you retook failed science courses. Calculating it accurately before you apply is essential for setting realistic school targets and preparing a GPA addendum if needed.
The Four AADSAS Sub-GPAs
AADSAS reports these four GPAs separately on the data report sent to every dental school you apply to. Understanding what goes into each one — and how it is calculated — is essential for accurately estimating your application profile.
The AADSAS Formula
Quality Points = Grade Points × Semester Credits
AADSAS GPA = Σ(Quality Points) ÷ Σ(Semester Credits)
The formula is a weighted average: courses with more credit hours contribute more to your GPA than lower-credit courses. A 4-credit General Chemistry course earning a C (2.0) contributes 8.0 quality points — twice the drag of a 2-credit course with the same grade. This is why repeating a 4-credit science course with an F is so damaging to the BCP GPA.
| Grade | Points |
|---|---|
| A+ / 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 / WF | 0.0 |
| W | Excluded |
| P (Pass) | Excluded |
| AP Credits | Excluded |
Worked Example: The Repeat Effect on BCP GPA
This example shows how retaking a Biology course affects the AADSAS BCP GPA versus what a student's university transcript might show with grade replacement active.
| Course | Credits | Grade | Numeric | Quality Points |
|---|---|---|---|---|
| Gen Bio 1 (Attempt 1) | 3 | D | 1.0 | 3.0 |
| Gen Bio 1 (Attempt 2) | 3 | A | 4.0 | 12.0 |
| Calculus | 4 | B | 3.0 | 12.0 |
| Totals | 10 | 27.0 |
AADSAS BCP GPA
2.70
27.0 quality points ÷ 10 semester credits
Transcript GPA (with replacement)
3.43
Only the A and B count — D replaced and removed
The 0.73-point gap between the AADSAS GPA and the transcript GPA is entirely caused by the all-attempts policy. If this student applied without calculating their AADSAS GPA first, they could easily misjudge their competitiveness by nearly a full GPA point.
How to Use This Calculator
Gather every transcript
Collect transcripts from all post-secondary institutions — including community colleges, dual-enrollment high school courses, transfer institutions, and any international universities. If there is a transcript, AADSAS requires it.
Categorise by academic level
Sort each course into Undergraduate, Graduate, or Post-Baccalaureate. Courses from your bachelor's degree are generally undergraduate. Post-degree coursework (e.g. DIY post-bac or formal post-bac programmes) is post-baccalaureate unless it was part of a graduate programme.
Assign a subject type to each course
This is the step that sets AADSAS apart from other CAS calculators. Assign Biology, Chemistry, or Physics for BCP courses; Math or Other Science for additional science courses; Non-Science for everything else. This determines your BCP GPA and Science GPA.
Note the credit system
Identify whether your institution used semester or quarter credits. Quarter credits are automatically converted by multiplying by 0.667 — select 'Quarter (×0.667)' in the dropdown and the calculator handles the rest.
Enter every attempt, including repeats
Add both the original attempt and any retakes as separate rows with their respective grades. AADSAS does not recognise grade forgiveness — include every F, D, and retake regardless of what your transcript currently shows.
Handle special grade types
W (Withdrawal): enter it — no GPA effect. WF (Withdrawal-Failing): enter as WF — counted as 0.0. P (Pass): excluded from calculation. Fail in a P/F course: enter as F. AP credits on transcript: enter with 0 credits or leave a note — they are included but carry no weight.
Calculate and review all four GPAs

Applying to medical school as well?
AMCAS uses a very similar all-attempts, quality-points formula with its own course categorisation system for science vs. non-science GPA.
