The book is direct, to the point, and does indeed help you set up your HP 33s with engineering equations.But that's about it. The HP33s isn't really that user friendly a calculator to input a lot of formulas into, and on the FE exam the formulas are actually in the reference manual. Having to look up which formula I entered into the calculator while doing a practice test took longer than looking it up in the manual and writing the formula in the margins.Good book...just not very useful.
