I took New York State Regents physics in 11th grade back in high school. I've always had a skill for math, but after taking Regents physics all I thought was, "Meh, that was fun." When I got to college I decided to give physics another go, and since I had some advanced math experience, I chose a course called University Physics (which is calculus based, over the strictly algebra based "College Physics"). Moore's Six Ideas were the required texts -- the first three units (C, N, and R) covered in the first semester, and units E, Q, and T in the second semester.
Moore's books literally changed my life. After taking University Physics, I fell in love with the subject again, and am now a junior undergraduate majoring in both math and physics. My only regret is that I sold Moore's texts back after completing the course, as I needed the money. I wish I still had them for references, and chances are I will end up buying the set again for just that.
