All topics on this DVD are taught by working example problems. We believe in teaching-by-doing and that is what you will receive by watching this DVD.

We begin with the easier problems and work our way up to the harder problems. The student immediately gains confidence, does not get bored, and quickly feels like he or she can conquer the material. This method is extremely powerful and has proven itself time and again. Perhaps most importantly, problem solving skills are honed early on that will help with homework and taking exams even after watching the very first lesson.
