39 FE Exam Prep Resources [Free and Paid]
Here's a collection of the FE exam resources that are available, some are free, some are from commercial providers, universities and engineering societies. Also be sure to check out the other resources: the Best Calculator for the FE Exam, the collection of FE Practice Exams and all things related to the FE Exam.
It's important to realize that the FE exam used to be split into a common-to-all-disciplines morning exam and a discipline specific afternoon exam. Starting in early 2014, there are only discipline specific exams so you'll see some resources that have not updated. Also you'll see some resources that host a generic review class to cover all disciplines.
This isn't a big deal if you aren't paying much for the course or if the resource is free. Yet, keep in mind you'll have to fill in some gaps on your own. But if you decide to spend big money for a review course, ensure it is discipline specific. As always the power is in practicing exam questions and not just theory, so be sure your choice works through plenty of NCEES style problems.
