All of these sites are official recipients of the Kelley Headbutt of Excellent Award, pictured below in all its glory. Stop by and tell 'em Calculus-Help.com sent ya.

• MathGV: A powerful graphing program for the PC, and best of all, it's free. All of my software graphs are generated by this fantastic program.

• Calc101.com, a web page that does any derivative or integral step by step with explanations (there is a small fee for integrals).

• Alvirne's Problem of the Week has weekly problems written by students.

• Hotmath.org: Having trouble figuring out odd problems in your Algebra, Precalculus, or Calculus textbook? This incredible (and somehow free) site provides step by step explanations for most of the major textbooks out there. It won't just give you the answer if you don't want--instead, you can opt just for a step ot two in the right direction for guidance. I highly recommend it!

• Ask Mr. Calculus: This kind man will answer your calculus questions if you e-mail him. Please do not send any questions to Calculus-Help.com, as time constraints do not allow me to answer them.

• Karl's Calculus Tutor: Very in-depth explanations for any calculus concept you could imagine

• Mrs. Carlton's Algebra I & Little Rascals Tutorial Page: An entertaining and incredibly well designed math page, sort of like this page, except for Algebra students.
