The AMCAS GPAs are standardized GPAs that medical schools can use to fairly compare the academic records of applicants who have attended undergraduate and graduate institutions that use different academic calendars and grading systems. Your AMCAS GPAs are calculated during verification and will be listed on your printable application once AMCAS processing is complete. You will also be able to view your Cumulative Undergraduate GPA and your Graduate GPA.
AMCAS GPAs almost always differ from those calculated by the school(s) you have attended. The AMCAS program does not attempt to compare AMCAS GPAs with those that appear on your official transcripts.
The formulas the AMCAS program uses to calculate AMCAS GPAs are available in the Grade Conversion Guide.
