The ThinkFast game in Module 1 sometimes works too fast. If you encounter this problem, you can retake the game to answer any of the questions that went by too fast. Or, you can try the non-Flash version, though that too is timed.
If you think you have found a bug, please email us and let us know what make (Firefox or Internet Explorer) and version of browser you were using when you encountered the problem.
We will add to this page as bugs are identified.
