The PE Resource Guide
Example of a PE Stamp
One of the main reasons for coming to this site is for help on passing the Professional Engineering Exam. This is the test which engineers must take to become certified. I would equate it to being similar to a lawyer before and after they pass the bar.
In time, I hope for WIkiEngineer to develop a study guide which you will be able to follow the links and gather a greater understanding (with examples) of separate topics. There will also be other aides to help you pass.
