Practice exams are a proven tool to increase retrieval of information long-term. Over a three-year period, students in Anatomy and Physiology I and II were offered practice exams as either no-stakes practice exams (years 1-2) and low-stakes practice exams (year 3). Students who took practice exams did significantly better on the actual lecture exams, leading to better grades and higher passing rates for our courses. There was no difference for gender and student population. Students earning credit (low-stakes) were more likely to take the practice exams but their scores on actual exams and their overall scores were lower than those of students who did not earn credit (no-stakes).
