In this module, you'll learn all of the concepts, techniques and strategies needed to answer word problems on the GRE. In particular, this module covers:

 Assigning variables Writing equations Testing the answer choices Age questions Motion questions (distance-rate-time) Work questions Double-matrix & Venn diagrams General sequences Recursive sequences Sums of sequences Growth tables Mixture/solution questions Variables in the answer choices

### Two ways to prepare

Beneath most of the video lessons below, you’ll find a Reinforcement Activities box containing practice questions that are specifically related to the concepts covered in that lesson (e.g., the lesson on work questions). With this lesson format, you have two study options:

• Watch the video lesson first and then reinforce your learning by answering several related questions, or…
• Tackle the practice questions first and watch the lesson only if you need help with the concepts the practice questions test

For more on this learning strategy, read the “How to Beat the GRE” section of our course overview page.
