These 4 new MCAT scaled scores are combined to create a total score that will range from from a lowest possible score of 472 to a highest possible score of 528, with a midpoint of 500. Achieving the highest possible scaled MCAT score (528) is rare but achievable. Medical school admission committees only use scaled scores to evaluate the MCAT component of the admissions process (not percentage, not percentile). Choose an MCAT course to suit your needs.
