While the website is (usually) easy to use, the content often has typos and doesn't feel like it was proofread, especially in quizzes. Used this to study for an exam and it is largely supplemental and not any more beneficial. In fact, taking the license exam's practice exam are more helpful both in style and the feedback/explanations for why answers are correct. Use the money you would for these courses for the reference materials instead.Update: As most of these reviews have after posting, someone from PPI gives a generic response, then they email you and ask for more info, and you provide it and then they just don't give any response from there. Looks like a common theme in the other reviews; buyer beware.
