You can do it, we can help!

We believe that all students deserve access to an excellent education... at a reasonable price. We know it isn’t easy to prepare for the GRE® on your own. With this in mind, we created the Greenlight course, your fast track to GRE success. Greenlight is an affordable exam preparation course featuring more than 500 high quality videos (over 31 hours!). To help you get the most out of the lessons, we also created a free, comprehensive Study Guide that acts as your personal roadmap to GRE success.

Our secret sauce?

We actually care about your academic success. The Greenlight course was developed by professional instructors and curriculum planners who know exactly what it takes to test confidently and score higher.
