Preparing for SW Cert. tests

I'm looking to get SW Certs. in these 3 areas. I have never taken a SW test. So I am unsure of what to expect. Is there a book or site to prepare?

I want to do this to show inititive and self improvement at my current work place. They are big on this.

CSWPA-Sheet Metal

CSWPA-Drawing Tools

CSWA

I do feel I have the abilities to successfully pass these exams, but I also have no idea of what to expect from them. Any pointers in the right direction would be greatly appreciated.
