I had a plan to work all NEC, then another pass for each topic.
I go there and just worked them all in order, with a note for ones that I couldn't find what I needed quickly. Finished about 45 minutes early for each portion. I'm actually glad I did it that way. Saved time for not having to go through it multiple times. I used the EERM, NEC, and my binder for 80% of the questions.
