Susan, I greatly appreciate this list and will definitely come back to use it as a reference if I need a book recommendation. (I don't think I'm the target audience, although who knows what the future brings..) That being said, I think you are missing out on an opportunity to reach a wider audience. It bugs me a bit that the requirements seem very American-centric. What I mean is the following bit: > A high school education — which should include pre-algebra, algebra 1, geometry, algebra 2, and trigonometry — is sufficient. And later the paragraph on "pre-calculus". I know that many places don't have such names for courses in high school. In fact, often it's just called "Mathematics" and you either take it or you don't (obviously there is a spectrum here). How is a prospective (non-American) student to know what is covered in Algebra 2 in an American high school? I'm not asking you to change the article, I just hope I can nudge you into realizing that the text as it is now is more difficult than it needs to be for non-Americans.
