My name is Pete, I'm an operational nuclear engineer in the U.S. Navy. However, I recently had shoulder surgery, so the Navy stuck me at a desk with little to do while I recover. So I am writing study guides for CLEP and DSST exams. It's a great way to study for the exam. If you want to write one, I can send you a pdf of the fact sheet. They're free to us military types, but I think most people have to pay for them. Use the fact sheet as an outline, but make sure to put the ideas in your own words. Wouldn't want to violate any copyrights.
