The FE Exam is three months away. If you are taking the FE in October now is the best time to start getting ready. Start with practice problems. There is nothing better for preparing for the test than to work problems similar to what you will find on the exam.

There are a lot of sources for practice problems. Search any book store for sample exams. You can also find several website with 
practice tests and sample problems. My favorite is eitexam.com. I especially like their 10 minute quizzes. It’s easy to find time to do a quick 10 minute quiz. It’s not so easy to find the time to do a four hour practice exam. They also have full instructions on how to work the problems and explanations why the answers are right or wrong. And finally they have both general exam and civil specific questions. All for only 15 bucks for three months.

That’s enough free advertising for now. Whatever method you choose, find one that works for you. Also find regular time to practice and study. Remember to get a copy of the Supplied-Reference Handbook from the NCEES website. The 
pdf version is free. Or you can have a paper copy mailed to you. You can check out the study material that NCEES sells as well. It’s not cheap, but hey, they wrote the test, so they know what’s on it.
