Cengage is the most worst application for learning that schools still use for some reason. The interface is horrible and glitchy; the amount of times I've entered the correct answer and it still tells me I'm wrong is incredibly infuriating. They even have the correct answer shown after the question is answered and it still matches up with my answer, yet it says I am wrong. The people who made this software are incredibly lazy and obviously have no plan on fixing their horrible website. This website actually makes learning the subject harder because I get stuck on the same glitchy problem. If you made this software, there's a special place in hell for you.
