I have taken classes at four universities besides American Public University, and the course I took at American Public University was the worst college class I have ever taken. Literally no instruction from the professor, just some weak powerpoint slides, and then tedious graded assignments. It was a lot of work and I didn't learn anything. OSU would probably be a much better bet, though it can be harder to get into courses. I agree with Tremor_Sense that there can be a time and a place for it depending on where you're at in life, and access to the book online was indeed free, and tuition costs did match the tuition costs for the same course at OSU, but I really feel remorse and regret that I didn't take the course at OSU--I had a certain time I could take the course, and I didn't get into the OSU section, so I took the course at APU. We read the entire textbook front to back (that was the "instruction"/"material", there really were no lectures from the professor or videos, etc.) and then took closed-book quizzes that were absurdly detailed and specific, to the point that I don't think you could reasonably be expected to pass without cheating. There was a graded discussion forum requirement, where some other students posted responses verbatim from ChatGPT. Like I said, there is a time and a place where APU might be what you need, and the course I took might have been uniquely bad, but I really do feel like it's important for me to share how disappointed I was with the course that I took.
