His philosophy about teaching is that a person needs to truly understand the concepts, rather than simply memorize a rote formula.
Many of the techniques he shares were developed by him personally and tested on his own students.
Each unit in his books contains problems from various levels of difficulty, from level 1 to Super Einstein level.
The books are very helpful in teaching quick solutions to real life and often challenging dilemmas. He always teaches in context of real world situations.

These books give you the data and teach you how to do the calculations to come to your own conclusions. The books do not just provide the answer, they explain the answer.
