Optional Activity Points (OAPs) are extra credit points students can earn in class. For every hour spent on optional extracurricular activities related to the class, students earn 5 OAPs. Students can earn up to 50 OAPs for 10 extra points or 100 OAPs for 20 extra points towards their grade. Suggested optional activities include taking the GRE, studying GRE materials, taking practice GRE tests, researching graduate schools, attending presentations, working on applications and personal statements.
