  • Photo: We required a passport-sized photo (2 inches by 2 inches) for identification purposes. This must be sent in via postal mail. These photos can be easily obtained at Walgreens, CVS, and many other locations that offer photo printing.

Applicants must have a baccalaureate degree from an accredited college or university. The degree must be awarded and visible on an applicant’s transcript at the time of application. An applicant must have achieved a minimum cumulative grade-point average of 3.00 on a 4.0 scale. To calculate a cumulative GPA, all hours attempted and points awarded are used with the exception of pass/fail courses and those courses from which a student has officially withdrawn. Some universities exclude the points and or hours from courses that have been repeated. In order to make a fair comparison of applicants, calculations must be standardized and therefore these courses are re-included when calculating cumulative GPA. The total number of points awarded is divided by the total number of hours.

The following courses are required and must be completed with a letter grade of C or better:

  • 8 hours (or 2 classes) – Chemistry (with lab)
  • 8 hours (or 2 classes) – Biology (with lab)
  • 6 hours (or 2 classes) – Human Anatomy and Physiology
  • 3 hours (or 1 class) – Physics
