5 Stars Out Of 5

My son just completed a home school co-op chemistry course that used a challenging textbook. He finished with the highest grade in the class. In preparation for the class, we started watching these DVDs the summer before class started and continued periodically throughout the school year. The instructor is engaging, humorous without being silly, and effective in his explanations. We loved it. He set a positive and enthusiastic tone, and piqued interest for my son as he started his class last fall. Although strictly a supplement, I feel it was an invaluable resource that contributed to my son's interest and success in his class and I highly recommend it!
