These are two sites which should prove useful to FEs preparing for the NCEES Professional Engineering Exam:
1. Passthecivilpe.com This site provides lists of reference books, overviews the depth exam specifications, provides a photo overview of NCEES permitted calculators, and even provides a unique list of books for each of the afternoon depth exams. You will also find many valuable resources like links to all the state boards, an easy to read list of NCEES exam day policies, and the just released PasstheCivilPE Guide Book. Check it out.
2. Engineerboards.com This is a forum. There are more than 450 topics with thousands of replies. If you have a question, and you need an answer, this is a great site to use. (You can also use the search box on the upper left of this blog.) The site administrator, ptatohed, provides very informative posts. He seems to know a great deal about the PE.
3. ppi2pass.com This is a site full of books, packages, online PE review courses, a forum, and a test generation platform to take practice PE exams. They frequently give special discounts, and you can always get another 5% off using the word mommy taught you, "PASS1114". (Seriously, put those eight letters in the discount code box at checkout.)
4. PE Exam Study Materials Store: The best rated PE exam materials, grouped together for easy comparison and shopping. Only the most current editions are listed.
