Had a similar thing at my college. If you are trying to take a language class, you need to take an online test to examine your current level of knowledge of the language, so that they can put you in an appropriate class level (i.e., basically allowing you to test out of beginner level classes, if you have enough knowledge to take the more advanced ones). I found out that all the correct answers were basically encoded into the front-end HTML, so it looked something like "return question1.result === "XYZ". While the value of cheating on such a test is extremely dubious (you do not get any credit on your transcript for the beginner classes if you tested out of them), I thought it was interesting nonetheless.
