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.

Great Beginner Course. There are some parts where there will be frustration, but the forums are helpful. Any type of class involving math and science involves practice and work. Professor is great!
