A great flashcard is more than just a memory tool. It can also help you overcome that “not sure what to do next” feeling on test day. Here’s how to get the most out of every flashcard you create.

You don’t need to memorize that many facts to conquer GRE Quant.

Nine identical machines, each working at the same constant rate, can stitch 27 jerseys in 4 minutes. How many minutes would it take 4 such machines to stitch 60 jerseys?

First, take a deep breath. In this article, you’ll learn a methodical approach that will work on GRE rates problems every single time. On test day, it’ll be tempting to throw away your new habits and go back to old ones. Try to do the opposite. You’ve done all of this studying for a reason!

Whenever you choose not to write something down, you’re taking away your ability to check your work for mistakes. (By the way, where’s the mistake in the logic described above?)

To start the problem, make a table. Your scratch paper should look like this: Read more
