Also gonna bump this thread again - I passed as well!
Glad to hear the SOPE course is helpful. I'd also like to plug the online class offered by IISE - I thought it was quite helpful as well. I also referenced the IISE class binder dozens of times during the exam.
Since I wish this had been here when I was prepping, I figured I'd give a breakdown of what I used to study.
Materials I felt were useful, in order of usage during the exam:
A Concise Reference Guide for the P&PE Industrial Exam - Daniel Bartlett (I seriously referenced this for 90% of questions; vital - I strongly suggest you get this).
The IISE class binder, as mentioned above
Kennedy's Review Guide
Kennedy's Review Test (this came for "free" with the IISE class)
A few binders with notes from college classes (Engineering Economics, Statistics, Operation Research, Mgmt Science, and Reliability & Quality Control)
The NCEES FE Review book (yes, the same one they allow you to use during the FE exam; has quite a few handy formulas/tables)
Industrial Discipline-Specific Review for the FE/EIT Exam (has a lot of practice problems, even though it's "only" for the FE)
I didn't use the following all that much, but I'm still glad I brought them (I did occasionally use these to double check something, or for random definitions/lookups):
Textbooks from college classes (I hadn't kept some of them after college, but I knew what I had used and went and bought old editions on Amazon for <$5):
Statistical Quality Control - Douglas Montgomery
Intro to Management Science (Hillier/Hillier)
Operations and Supply Chain Management - Jacobs Chase
Other books (I hadn't used these in college, but were useful):
Maynard's Industrial Engineering Handbook
Handbook of Industrial Engineering Equations, Formulas, and Calculations - Omitaumu
Introduction to Industrial and Systems Engineering - Turner/Mize/Case/Nazemetz
