This page is aimed at my students who are looking for resources beyond the textbook and homework problems.
While calculators and computers are not allowed on exams, learning to use them effectively will aid you in your applications of calculus in the future. See this list of math software packages to get started. I help develop Sage, and recommend it in particular.
There are many resources for learning calculus online. Here is a sample, but you should explore on your own!
