MCAT对以下方面评分：Verbal Reasoning，Physica Sciences，Writing Sample和Biological Sciences。MCAT考试形式随1991年MCAT administration的出台发生变动，旧式的MCAT考分已不被接受。
申请者可以参阅MSAR（Medial School Admission Requirements）得知MCAT考试的具体要求。MSAR可从医学院的医学预科咨询处索取，或通过填写APPLICANT PUBLICATION ORDER FORM来获得，通过该表格还可获得THE MCAT STUDENT MANUAL，从而了解MCAT考试的详细情况。
在MCAT考试时，申请者可选择将考试成绩通过AMCAS（AMERICAN MEDICAL COLLEGE APPLICATION SERVICE）直接寄至AMCAS-participating的学校，申请者还可指定六所non-AMCAS的学校向其免费寄送MCAT成绩。
如果申请者在MCAT考试时未选择免费寄送成绩服务，可事后将成绩寄至AMCAS，或填写MCAT ADDITIONGAL SCORE REQUEST（ASR）FORM来寄送成绩。
