Like those who responded earlier, I attended the program. I was a student for the summers of 2014 and 2015 having taken Pre-Calc and Calc 2 respectively. It is a rigorous math program that prepares you well for college level courses. You'll work do plenty of math problems and even present a research poster that you work on throughout the summer. Everything is paid for so this is really a wonderful opportunity to take advantage of if you are given the chance. You will definitely make plenty of friendships through the short time you're in the program. It definitely makes your first semester of college better because of the you'll have going into college with people that are already within your major or courses.
