The best explanations I've ever heard, everything felt so easy to understand. Also the humour of Ms. Dorian Canelas was really great and brought a very positive feeling when completing the course.

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.
