These colleges are Thomas Edison State College, Charter Oak State College, and Excelsior College. If you add the costs of the exams and the tuition of the colleges, you can earn a bachelors for between $5,000 and $6,000. That is all four years not just a year of college. You can also study for these tests and pass them much faster than actually taking the course. Plus, if I can pass a calculus test (or other test) that shows I've studied on my own and learned the material then I should get the credit.
