Thank you Professor Dorian A. Canelas! It made me much more easier to understand the basic principles of chemistry and it builds me a lot of confidence in answering some of the problems in chemistry.

I've found easier tutorials on YouTube for certain subjects but I really enjoyed the demos!

The lectures were difficult to follow, and the material on the tests were not covered well.

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.
