I bought this book together with Vaganova's handbook and a couple other resources. I admit that i learned more just from reading this book than i learned from some of my own dance instructors over many years. While i think it's necessary also to read other technical books for details on HOW to do these exercises, i do think this lesson plan leaves virtually no holes in students' strength, knowledge, or artistry. The thing that i found a tiny bit frustrating is that the exercises are REALLY hard, if you're not trained properly. For example, i tried to give exercises from the 4th Year Lesson 1 Plan in this book to students that were considered "Advanced" at a studio where i had just started teaching, and they literally could not do the exercises! And unfortunately, the 1st and 2nd year exercises are tedious for students used to being given steps that are too advanced and being allowed to botch them. So i would not recommend these lessons for "casual" ballet students (a term i detest!). I would recommend drawing from these lessons for students who are at the beginning of their ballet training, and starting with Year 1. I also found it helpful to watch videos of Vaganova students on YouTube. Sometimes one can find real Vaganova students doing the exact same exercises--and doing them correctly. It's very inspiring!
