Excellent course!!! I enjoyed the historical background the lecturer used including the brief synopsis of the Chinese emperor consuming mercury pills to gain immortality.

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.
