Frequently Asked Questions
Return to Top

Why did you create this service? This project was under consideration since writing the 2010 edition of The Top Academic Ohio High School report. After seeing the excitement that my friends had about the CBS 60 Minutes segment on Khan Academy, I thought that the time was right. I also liked the idea of trying another way to boost OGT results.

How many questions are included? Currently, all of the posted ones from the March 2009 test are included. Obtaining a large number of questions is not the goal -- I want all of the various types of questions and the videos necessary to solve those questions. To view the tests for the last few years, click on the following links: March 2008 Test, March 2007 Test, March 2006 Test, and
March 2005 Test.

How did you identify the current videos? I enlisted the help of my daughter and her friend. I even found a few. To make this work in the future, I will need to enlist the help of others, especially teachers, to identify the best videos. If you have other favorites, please click on contribute.
