Hi, my son attends TW classes.
The book was part of the registration package. If you are looking for more information on Right Brain Education, then the book is informative enough. It serves as a platform for getting your child prepared for these classes because as a parent, you must be aware of the techniques and truly believe for right brain education to work.
The DVDs are 8 min sessions with 4 lessons per DVD. Honestly, they are pretty boring because for speed training, my son has been doing 1 sec per card and TW flashes at a slower rate. The price is exorbitant if you ask me.I got mine secondhand from a friend There are better resources that you can for free via the internet and LR forum.
So, you must decide if you want information or materials
