This is an invaluable DVD to aid in your preparation for CAT, GMAT, Math Olympiads or any competitive exam that tests your basic Math aptitude.
This 25 hour 6-DVD brings the techniques from Vedic Mathematics and Trachtenberg System together. The DVD can be used as your personal coach, while the book can be used to practice and hone your skills. We have not attempted to do a comparative study of these techniques and make a judgment on which one is better. We have simply, presented the techniques in a sequence that makes most sense. There are inherent strengths in these two approaches. While looking at all the speed improvement techniques, we have ensured that we focus on techniques for defect prevention and error minimization as well. Speed coupled with improved accuracy must be our paramount focus during any problem solving process. This book attempts to elucidate several key techniques, examples and practice problem sets.
