You took SOPE. I did also, and managed to do far more than scrape by. Their notes needed a lot of highlighting in order to easily recognize headings, valuable information, formulas, etc. Also, create an index containing every heading/subheading so you can easily navigate the notes. I spent MANY hours just organizing this. Think my index, with 2 columns per sheet, was about 8 pages long... but priceless during prep and during the exam! Put the index and your custom formula cheat sheet into a paper brad folder so it's easy to use during the exam.
From what I recall, my main resources during the exam were SOPE notes, NEC, NESC, and Camara book (although Camara wasn't used for much). The CI practice test was pretty useless. NCEES and SOPE practice problems were very good. I also bought Grainger, Wildi, etc. but didn't really use them.
Re-take SOPE and pause the lectures to research topics yourself. The recordings are supposed to be 64 hours. I prob spent prob 3-4x that much time when going through the lectures, since I'd pause, Google a topic, and really ensure I understood it fundamentally. Things like PU, symmetrical components, +/- 30 deg phase between Wye and Delta, electromag machine mechanics, autotransformers, etc. Go beyond just passively watching the SOPE class and hoping you'll find the answer in your notes during the exam.
