My name is Dr. Steve Alexandris and I am posting about a site I have built for free GMAT math challenge question videos. I studied math undergraduate at Yale and have a PhD in mathematics from Massachusetts Institute of Technology and have been teaching math for 10 years and it is my passion. Check out my videos at YouTube - gmat's Channel. Questions courtesy of 800score GMAT prep (www.800score.com/gmat-home.html).
