It is a wonderful course for Middle school students. A first course in Chemistry, for the gifted students who will do AP Chemistry. Not suitable for adult learners who need an advanced introduction.

An exceptional course to revise previous concepts. many a times strengthened my previously vague concepts. The interviews and especially the practical videos were very enlightening.

It's really intolerable these MOOCs like this one that don't offer PDF support. The videos skim over the subjects, are messy and don't give enough examples. The trainer scribbles on the slides, making them illegible. The quizzes are all-or-nothing (you retake everything if you don't reach the threshold) and the advanced quizzes are ridiculous and useless. What's more, they're not corrected, so it's hard to understand your mistakes and improve. On the other hand, you can take them 15 million times if you have the patience.
