Permutations and Combinations suck. We all know it.

Counting problems (Combinatorics) are some of the most irritating questions that the GMAT has to offer, not in the least because these questions are things you most likely never even covered in high school!

That's right--learn something new for the GMAT? The horror...

Well, maybe. 

The best thing about Permutations and Combinations is that with a few simple tricks, you'll see that they're really not about complex calculations at all--there are really only three calculations you'd be expected to perform!--but they insist that you plan your approach carefully. 

Oh, yeah--those silly n!/r!(n-r)! things that GMAT books try to feed you simply need to die. If you're not plugging this crap into Excel, there's a much better way to do your P&C calculations...

It's certainly not rocket science, even when many people think it is! That's why this book teaches you step-by-step how to turn P&C questions, a common fear point, into a secret weapon in your GMAT arsenal.

Includes: 
--the Three-Step Approach to break down any P&C question
--how to distinguish a Permutation from a Combination once and for all
--why the standard P&C Formulas are stupid
--when to count up and when to count down
--when to calculate independently and add
--some stuff I've probably forgotten

P&C can be easy points. Do yourself a favor and learn them. This book will teach you how.
