Title: Better then an instructor !
Review: I bought this for my Son who is a Junior in high school. He took Calculus A/B in the 1st half of the year and signed up for B/C the 2nd half. Unfortunately, he found calculus B/C much more challenging so he decided to drop it and retake next year for college prep. Bottom line...my son says these are excellent. They show step by step for each problem & solution and they can be replayed time and time again. My 16 year old son highly recommends this product for anyone looking to get a better understanding of calculus A/B.
