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.

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.
