My 7th grader absolutely loved this curriculum. We used the tests and experiments. The book is not dry reading like most textbooks. It reads like a good book and holds the student's attention well. My son was always coming up to me to discuss what he had read in the book.
This is a great 7/8th grade science text! Dr Wile writes in such a way that is easily understndable and very interesting. It holds the attention of my ADHD son. The tests were a bit too complicated for us but I supplemented them with oral testing. He does suggest the student be taking or have had pre-algebra with this, but we did not have a problem in not having it yet.
