Total GMAT Math Excerpt: Rates


As you may know, this week I released the long-awaited Total GMAT Math. As promised, today I'm offering a free excerpt from the book. It's the entire section, which covers everything from the basics to much more complicated rate problems that show up on the GMAT. It also includes several drill and practice questions

Then there are between five and ten realistic practice GMAT problems to further help you master the subject.
