Medical School GPA Calculator
Last reviewed: 2026-10-02 | Written by the SmartCGPA team
Enter your courses once to estimate the GPAs AMCAS (MD), AACOMAS (DO) and TMDSAS (Texas) calculate from them. These are estimates: each service calculates your official GPAs from your verified transcripts.
Rules source
This estimate follows the rules each service publishes. Check these pages for the current wording:
How Each Service Calculates Your GPA
One transcript, three GPAs
AMCAS, AACOMAS and TMDSAS each calculate GPAs from your transcripts with their own rules. The same courses can give a different GPA in each service, which is why this calculator shows all three side by side.
AMCAS (MD)
AMCAS counts every attempt and does not replace grades. It reports BCPM, AO and Total GPA. An A+ weighs the same as an A.
AACOMAS (DO)
AACOMAS counts every attempt and does not recognize school forgiveness, academic renewal or grade replacement. It reports Science and Non-Science GPAs, with Math counted as Non-Science, and converts quarter hours at 0.667.
TMDSAS (Texas)
TMDSAS does not distinguish plus and minus grades. It reports BCPM and Non-BCPM GPAs plus overall, undergraduate, graduate and last 45 hours GPAs, and it uses all grades assigned.
AMCAS vs AACOMAS vs TMDSAS
| Feature | AMCAS (MD) | AACOMAS (DO) | TMDSAS (Texas) |
|---|---|---|---|
| Grade replacement | No. Every attempt counts. | No. Every attempt counts, and school forgiveness, academic renewal and grade replacement are not recognized. | No. All grades assigned are used. |
| Science category | BCPM (Biology, Chemistry, Physics, Math) and AO (all other) | Science and Non-Science, with Math counted as Non-Science | BCPM and Non-BCPM, plus overall, undergraduate, graduate and last 45 hours GPAs |
| GPA scale | Plus and minus grades; A+ weighs the same as A | Plus and minus grades, modeled like AMCAS in this estimate | No plus or minus: A 4.0, B 3.0, C 2.0, D 1.0, F 0.0 |
| Quarter hour conversion | This calculator multiplies by 0.667 | 0.667 | Two thirds |
AMCAS
AMCAS counts every attempt and does not replace grades, so both the original and the retaken grade for a repeated course are included. It reports BCPM, AO and Total GPA, and an A+ weighs the same as an A. For a dedicated AMCAS estimate, use the AMCAS GPA calculator.
AACOMAS
AACOMAS counts every attempt and does not recognize school forgiveness, academic renewal or grade replacement. It reports Science and Non-Science GPAs, with Math counted as Non-Science, and it converts quarter hours at 0.667. For a dedicated AACOMAS estimate, use the AACOMAS GPA calculator.
TMDSAS
TMDSAS does not distinguish plus and minus grades: A is 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0.0. It reports BCPM and Non-BCPM GPAs plus overall, undergraduate, graduate and last 45 hours GPAs. It excludes W, WP, CR and Q grades, converts quarter hours at two thirds, and uses all grades assigned. An A- is worth 3.7 at AMCAS and 4.0 at TMDSAS, so the same transcript can give a different GPA in each service.
Where to Find Real GPA Benchmarks
This page does not quote average GPAs or acceptance rates. Use the original sources, which publish current data:
- AAMC FACTS Tables A-18 and A-23 for GPA data on applicants and matriculants
- AAMC MSAR for school-level data on MD programs
- AACOM reports for DO programs
- TMDSAS statistics for Texas medical schools
When Your GPA Is Not Where It Needs to Be
Find out whether the gap is in science or non-science GPA
Use the calculator above to see where your deficit lies in each service. A gap in science GPA calls for targeted, rigorous science coursework, while a gap in non-science GPA points to a different plan. Diagnosing the gap first prevents wasted effort.
Consider a Special Master's Program before reapplying
Special Master's Programs are one-year graduate programs, often offered by universities affiliated with medical schools. Strong performance in one can show you can handle a demanding science curriculum, and it can provide letters of recommendation from faculty who know the medical school environment.
Apply to programs where your numbers fit
MSAR publishes GPA and MCAT data for MD programs, and AACOM publishes information for DO programs. Compare your own numbers with the published data for each school before building your list.
Use the GPA planner to project your trajectory before reapplying
If you plan to take more coursework, use the GPA planner to see how many credit hours of strong grades it takes to move your GPA. It usually takes more credit hours of A-level work than people expect, so plan the math before committing to a program.
