No. C&M students are fully engaged in underlying mathematical ideas. Dr. Francis Sullivan, Director of the Computing Laboratory of the Institute for Defense Analysis says this about C&M calculus courses: "For me the wonderful thing about C&M is that it concentrates on what calculus is about."
When I originally signed up to take C&M BioCalc for my freshman calculus course, my older brother tried to talk me out of it. He told me that I wouldn't learn anything, and that I would have trouble later on in my engineering classes. Out of stubbornness, I stuck with it. This past year, my brother came to me to ask my help. One of his mechanical engineering classes was filled with Calculus III material and he was having trouble. After I helped him, he said to me, "I wish I had taken a C&M course. I probably still would have forgotten all of the formulas, but at least I would know how to go about getting the answer."
