How to Calculate Your AMCAS GPA (Step by Step)

AMCAS recalculates your GPA using its own rules — and the number can differ from your transcript. Here is exactly how it works, including BCPM, repeat policies, and what counts as a science course.

ByElias Woodbury·
Key Takeaways
  • AMCAS includes every credit you ever attempted — including community college, dual enrollment, and failed courses you retook.
  • BCPM (Biology, Chemistry, Physics, Math) is determined by the AMCAS course classification, not your school’s department.
  • AMCAS counts both attempts of a repeated course — unlike many undergraduate institutions that only count the most recent grade.

How AMCAS Calculates GPA

AMCAS recalculates your GPA from scratch using your transcripts — it does not use the number printed on your final transcript. AMCAS assigns standardized credit values (semester hours) and converts your letter grades to a 4.0 scale using its own published table.

It then computes several GPAs you will see on your verified application:

  • Cumulative GPA: All college coursework you have ever taken.
  • Science (BCPM) GPA: Biology, Chemistry, Physics, and Math coursework only.
  • Non-Science (AO) GPA: Everything else — humanities, social sciences, etc.
  • By-year GPA: Freshman, sophomore, junior, senior, postbac, and graduate breakdowns.

What Counts as BCPM?

Course classification is determined by AMCAS, not your university. The AMCAS Applicant Guide publishes course classification rules — and they sometimes differ from how your registrar categorizes a class.

  • Biology: General biology, anatomy, physiology, microbiology, immunology, genetics, neuroscience (often), biochemistry, cell biology, ecology.
  • Chemistry: General chemistry, organic chemistry, analytical chemistry, physical chemistry, inorganic chemistry.
  • Physics: General physics, engineering physics, biophysics.
  • Math: Calculus, statistics (including biostatistics and behavioral statistics), discrete math, linear algebra.

Borderline cases — exercise physiology, computational neuroscience, or interdisciplinary courses — should be classified based on the course description and content, not the department offering it. AMCAS verification staff may reclassify a course you marked incorrectly.

How Repeated Courses Are Counted

AMCAS counts every attempt of a course you repeated. If you earned a D the first time and an A the second time, both grades factor into your GPA. Your home university may apply grade replacement that only shows the higher grade on your transcript — AMCAS does not.

This is why your AMCAS GPA can look noticeably lower than the GPA on your final transcript.

Special Cases (AP, IB, Pass/Fail, Withdrawals)

  • AP/IB credits: If awarded without a letter grade, they do not factor into AMCAS GPA. They still count toward total credits earned.
  • Pass/Fail courses: Pass grades do not factor into GPA. Fails count as 0.0.
  • W (Withdrawal): Does not factor into GPA but appears on your record. Excessive Ws can be a flag.
  • WF (Withdraw Failing): Treated as an F (0.0).
  • Audit: Does not count.

Verifying Your AMCAS GPA

After AMCAS verifies your application, review every course classification carefully. The AMCAS portal allows you to request changes during a brief window via the Academic Change Request process. If you believe a course was misclassified, submit the course description and syllabus as evidence. Changes that benefit you (moving a course into BCPM, fixing a typo in grade) are worth pursuing; trivial changes are not.

Frequently Asked Questions

AMCAS includes every grade you ever earned in college coursework, including failed courses, repeated courses (both attempts), and any community college credits. Your home university may apply grade replacement or exclude certain credits — AMCAS does not.

No. AP and IB credits without a letter grade do not factor into AMCAS GPA. However, if your AP credit substitutes for a prerequisite (like General Chemistry), some medical schools will require you to take a higher-level course in that subject to fulfill the requirement.

A standard W does not factor into GPA, but it does appear on your AMCAS record. WF (withdraw failing) counts as an F. Excessive withdrawals can raise questions even if your GPA stays high.

Biochemistry is classified as Biology in AMCAS BCPM. Biostatistics is classified as Math. Behavioral statistics and psychology statistics typically count as Math, but you should follow the AMCAS course classification guide carefully.

Yes. After verification, AMCAS gives you a window to review and challenge course classifications. Submit changes through the Academic Change Request — but you must provide course descriptions or syllabi as evidence.
