Posted on March 25, 2011 by

In this GMAT video, Rich begins by presenting a sample DS question. The question tests your ability to solve for the value of an expression — without necessarily solving for the variables in that expression. Jess and Rich then go on to explain the best way to solve for one variable in DS problems in which you are given more variables than equations.

In addition, they provide a helpful recap of all the tips covered in this quantitative strategy lesson — if you haven’t watched all the videos, be sure to check them out!

    Very inconvenient to watch, fonts are really small, not easy to actually see something.
    I am using Windows Explorer.

      Hi Eva,

      If you click the double-sided arrow at the bottom right of the video player, the lesson will expand to full screen mode. That should make all the text much more readable.

      When you’re watching an on-demand lesson inside our course, all the videos expand to fit your screen.

      Hope that helps!

        Sorry, I missed that, I found out after I looked at another video.
