Airman 1st Class Amanda Cervantes, a student in the Medical Education and Training Campus Pharmacy Technician program on Joint Base San Antonio-Fort Sam Houston, conducts a mock exam to learn how to use the Composite Health Care System database. "Mock" exams test the skills that the students have learned to prepare them not only for the graded exam, but for what they will see in the clinical training phase and eventually in their permanent duty station. Cervantes, a widow with four children, joined the Air Force Reserve to set an example for her children, serve her country, and work in the medical field so she can help people.
