The course layout is incredibly sloppy for how much they charge. They brag about being able to make "custom" quizzes, but the quizzes are completely randomly selected from bulk question banks. If you are struggling with a specific type of question (i.e. uniaxial loading deformation), you can't focus in on that type of problem, you can only generate a quiz of random questions from their "Mechanics of Materials" question bank. For how much this costs, there should be a lot more structure to the course setup. Some of the "home works" give questions that aren't even related to the home work topic. I'd give this three stars, but this should be a lot better for the price tag. The recorded lectures were good, everything else was pretty unacceptably low quality.
