"I looove your rates process. I think I finally understand it!" -- Camila M Do you struggle with GMAT Rates questions? Let me guess: most GMAT questions seem OK, but you just can’t figure out why you’re not succeeding with Work and Rates questions. You’re a smart person. The rest of it’s working. Why are Rates posing such a problem? Believe it or not, you’re not alone. There’s actually a pretty simple explanation for this problem. Work and Rates questions aren’t really “math questions” in the same way as the rest of the GMAT. They require a bit more practical, real-world type of problem solving. You may even be looking at this book because nothing else has worked. There’s a reason for that, too: most GMAT books teach a lot of complicated, over-technical variations of Rates questions and then ask you to learn specific cases in which to apply specific equations. This is nonsense. By focusing on the practical aspects of Rates questions, we’ll be able to better understand how one simple framework can essentially answer every single Work or Rates question. With just a little bit of guidance in how to apply math to real-world situation, you’ll be able to break down any GMAT Work or Rates question and figure out how its moving parts fit together. Throughout the text, you’ll see as many relevant variations on Work and Rates questions as possible, but remember that it’s hard to be absolutely exhaustive. At 50+ pages, this guide definitely covers quite a few variants you’re likely to encounter. It Can’t Really be that Easy No one said it was going to be easy--it’s just not as bad as you might think! How to Beat GMAT Work and Rate Problems will teach you how to tackle every conceivable variation of Rates questions in a way that ramps up difficulty until the fattest, most evil Rates questions finally seem achievable. Even if you think Rates questions aren’t that big a deal, you might just find a few ways to clean up your thinking--and that’s never a Bad Thing on the GMAT. The YGC GMAT Rates Guide will teach you: --How to fit any GMAT Work or Rates Question into One Simple Framework. --How to Set Up Rates Questions Tidily the First Time. Every. Single. Time. --Clear, Non-Technical Approaches to GMAT Work and Rates Questions. --You know, more stuff. No one reads the technical stuff. Do you find math really boring and stuff? Do your eyes just glaze over when you’re reading equations? Are math people boring and funny-smelling? Yeah, it’s a problem. Rather than shove all this boring stuff down your gullet with a ton of technical language and a different equation for any number of abstract circumstances, the How to Beat GMAT Work and Rate Problems is written to be read quickly. Want to revisit it? Just read it again. There’ll be something for the GMAT beginner as well as the 680-scorer who just needs a bump over the 700-mark. Sometimes it’s just not enough to see the questions worked. That’s why, as a gift for purchasers of the YGC GMAT Rates Guide, I’ve put together a mini video course with worked explanations of eight different ultra-difficult GMAT Rates questions. Each of the eight videos comes with a set of notes regarding that particular problem. Read the notes to understand the talking points in the video--and also have a hard copy of the problem in front of you. If you’ve ever worried about GMAT Rates questions, this is the guide for you. What’s the best way not to see more GMAT Rates questions? Get them right.

Understanding GMAT-specific grammar is crucial to increasing your Sentence Correction score.  What is GMAT grammar? It's whatever the writers of the test want it to be.  There is always an objective reason that one answer choice is "more correct" than the others. Learning to identify WHY these sentences are preferable is the problem. You're certainly not going to find the explanations in the Official Guide (e.g. "this sentence is awkward.").  In this set of videos, Rowan Hand, author of the #1 Amazon Bestseller (GMAT and Test Preparation), Last Minute GMAT Grammar, breaks down necessary GMAT-specific grammar concepts in clear, easy language. Never again will you have to worry about picking the sentence that "sounds correct" but isn't precise enough, or the sentence that "sounds wrong" but is correct for some reason. Designed for both native and non-native English speakers, Complete GMAT Grammar Basics Part I provides as close to a comprehensive review of the nuanced, GMAT-specific grammar concepts as possible.
