I want to thank MPS for the work we did in Calculus and Vectors as well as Advanced Functions; it is really helping me a lot!  I have become friends with a guy on my floor in residence and he was complaining about his high school not teaching him some important concepts. That talk with him made me realize the importance of the work MPS gave me.  I am grateful for that, and please tell my friends at MPS that what you’re teaching them is very important, and that some students don’t get that important information that you give!
