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.

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.

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.
