<p>Good stuff. I would also strongly recommend one book, G. Polya's How to Solve It, which I only recently read and wish to goodness I had read before embarking on my undergrad math major (actually, it's a great book for a high school student with a math knack who wants to get to the next level).</p>
<p>PS - I had Steve Maurer, author of the last link, as a teacher in high school. He was a great teacher and a great guy, and I'm pleased to see he is now chair of the Swarthmore math department.</p>
