Materials that are not for public consumption (read: exercise solutions) will be placed in the class lockbox; username and password are available from the instructor.

Since we will largely build off of material from the first three semesters of calculus, I have dug up the review sheets that I handed out, from the last times I taught each of those courses, and placed them in a directory for your review.

A site called SOS Math offers pages of material on topics ranging from polynomial long division, the quadratic formula, and trigonometric identities, to Taylor polynomials, the Cauchy-Riemann equations, and Matrix algebra.
Another site covering similar material, including solved homework problems for you to practice on, is kept in Belgium.

Dan Sloughter has a web page containing Java programs for visualizing various mathematical concepts. My favorite is one which will draw the Taylor polynomial approximations for y=sin(x) .

A site called Karl's Calculus Tutor currently covers most of what would qualify as first-semester calculus, and some of the second semester, as well.
