Medical School GPA Calculator (AMCAS)

AMCAS GPA is a standardized GPA calculated by the American Medical College Application Service to allow medical schools to fairly compare applicants from institutions with different grading systems. It almost always differs from the GPA on your transcript because AMCAS uses its own grade conversion scale and includes all attempted coursework — including repeated courses and failures — that your school may have excluded.

BCPM stands for Biology, Chemistry, Physics, and Mathematics. AMCAS separates your GPA into a BCPM (science) GPA and an All Other (AO) GPA. Medical schools pay close attention to your BCPM GPA because it reflects your performance in the sciences most relevant to medical training.

AMCAS uses a 4.0 scale. A+ and A both equal 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, C+ is 2.3, C is 2.0, C- is 1.7, D+ is 1.3, D is 1.0, D- is 0.7, and F is 0.0. Quality points are calculated by multiplying the grade point value by the number of credit hours for each course.

Yes. Unlike some universities that replace a repeated course grade, AMCAS includes both the original and repeated course in its GPA calculation. This means repeating a failed or low-grade course will improve your GPA but the original grade is never erased from the AMCAS calculation.

Most MD programs admit applicants with BCPM GPAs of 3.6 and above, and top-tier schools often see median BCPM GPAs of 3.7–3.9. DO programs tend to be slightly more flexible. A BCPM GPA below 3.0 is generally considered a significant red flag and may require a post-baccalaureate or SMP program to demonstrate academic improvement.

AMCAS is the application service for most MD programs. AACOMAS is used for osteopathic (DO) programs and calculates a BCP GPA (Biology, Chemistry, Physics — math is excluded). TMDSAS serves Texas public medical schools and has its own grading conventions. Each service has slightly different rules for which courses count as science and how grades are weighted.

AMCAS converts quarter-system credits to semester-equivalent credits using a conversion factor of approximately 2/3 (one quarter credit equals about 0.667 semester credits). This calculator assumes semester credits by default; if your school uses a quarter system, divide your quarter credits by 1.5 before entering them.

AMCAS calculates your official GPA during the application verification process after you submit. You can view your Cumulative Undergraduate GPA and Graduate GPA on your printable application once processing is complete. Using a calculator like this one beforehand gives you a reliable estimate so you can gauge your competitiveness and plan your course strategy.
