Which should you take first?
Use the first condition that fits you. The right answer is the one your school will actually accept for your degree.
Are you currently in high school?
Consider AP first if your school already offers the course and exam. You get teacher support, a built-in schedule, and a familiar May testing window.
Are you an adult or already enrolled in college?
Start with CLEP. It has broad acceptance, year-round scheduling, and a low exam fee compared with paying per credit.
Are you active duty, veteran, or military-connected?
Check DSST and CLEP funding. DSST says DANTES can fund first attempts for eligible military students, and College Board lists CLEP military benefits.
Want the fastest possible path?
CLEP usually wins because you do not have to wait for May. Verify the exam first, study for the closest requirement, then schedule the test.
Five exams can change the whole semester.
