I needed to fulfill a couple prerequisite courses for a grad program, so I went to Study.com as an easy, cheap path to doing so. I was already very knowledgeable about the course content because of overlap with my work experience and my first master's degree.
I was absolutely shocked at the low quality of the material: typos galore, but more egregiously, tons of completely incorrect information. Just wrong. There were many test questions with multiple correct answers or no correct answer because the content writers clearly don't know what they're talking about. The lesson texts themselves also contained a lot of incorrect information. I couldn't believe that the standards are so low for allegedly college-level courses—it was an absolute disgrace.
It is very apparent that Study.com does not hire qualified writers and reviewers. If you need to knock out a few credits with no regard for actual learning, go for it. But this company should be ashamed of their subpar product.
