Excellent course. Although, it was very challenging to me to complete it and I had to repeat some of the videos, I am very happy that I decided to take it. It helped me to repeat my knowledge.

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.
