Saylor Academy is also credit by exam.  One exam at a cost of $25 if using online proctoring, totally free if you can find a proctor on your own.

I've heard about that. Who can I use as a proctor? Does it have to be some particular person such as a librarian, or could it be like a family member?

I don't know about Saylor's specific policy, but most proctoring requirements follow similar rules. Usually, they are looking for an unbiased trustworthy person that understands academic integrity. Typically they require someone with a college degree and specifically disallow family members or people who live with you.

Most librarians and colleges can perform this service, and of course, there are companies that perform proctoring as a full-time thing (though cost more than the $25 you could pay via ProctorU).

I looked into this a while back since my wife is a college professor and I figured would make a great proctor. The problem is that she lives in the same house so is therefore specifically excluded by most proctor agreements.
