The MCAT (Medical College Admission Test) does not have a mean score of 50 with a standard deviation of 10. Historically, the MCAT has used a scoring scale with different means and standard deviations, and more recently, scores have been reported on a scale from 118 to 132 for each of the four sections, with a median and midpoint score around 125 per section, not a mean of 50 with a standard deviation of 10.
