Excellent lecture videos with practice problems that are very helpful in recalling the chemical concepts. Really wish this course could offer at least an SOA so learners can be more motivated.

Excellent course. If you are struggling with high school chem, or need a good foundation for college chem - this course moves you through the concepts and gives you lots of practice problems.

The material was good, but I did notice a couple of lectures and in-course questions presented out of order. What really turned me off, however were quizzes. In weekly quizzes the first answer was always the right answer. In the final quiz most of the questions had the first answer as the right answer. Since randomizing the answers is so obvious and easy, I am really at a loss why the quizzes would be presented in this way.

kind of boring and I am not learning how half this info is obtained or why it is relevant to real world chemistry
