Premedical students who were preparing for the MCAT were recruited through premedical advisors and student organizations at various undergraduate institutions. The students were from Las Cruces, New Mexico, and the surrounding regions, including both rural and urban areas, and enrolled in school at New Mexico State University, University of Texas at El Paso, and other colleges in the geographic region. Registration for the course included required completion of an enrollment form in which personal data comprising name, date of birth, sex, race/ethnicity, current place of residence, and prior coursework were collected. To be eligible for the course, completion of prerequisite work in chemistry, biology, and physics with a minimum 3.0 grade point average on a 4.0 scale was required. The enrollment form also contained several questions designed to gauge motivation of the participants for taking the course and commitment to attendance. A question inquiring about passion for pursuing a DO or MD degree was also included to assess interest in a career in medicine.
