The average MCAT score each year is somewhere around a 24 (8 in each section). A good (competitive at most MD schools) score is around 30 and a stellar score is somewhere above a 34 to 36 (competitive at the top medical schools in the country). A score of 36 or better would put you in the top 2% of the country.
Each individual section on the exam is scored using a 118 to 132 range, with a median score of 125. You'll receive a score for each section, plus an overall score. Total scores will be centered at 500, with ranges from 472 to 528. MCAT registration is done online through the Association of American Medical Colleges.
