About the Book

The Graduate Aptitude Test in Engineering (GATE) essentially examines the aptitude of an engineering graduate. It differs from other examinations as it calls for an aptitude based learning and approach on engineering topics. To qualify this exam, an aspirant should have perfect understanding on the fundamentals concepts, and requires ability to interpret the fundamental quantities and their relationships and apply them to problem solving.
