Well, I'm in the first Calculus-based introductory physics course. It's my first physics course since high school in 2002. I think I'm doing fairly well. The first exam is next Thursday. I want to do the very best that I can in this course as it is laying the foundation for the road ahead. What key concepts should I focus on? What problem-solving skills should I make sure I acquire? Any advice is greatly appreciated. Thanks.
