Welcome to you Foca Se. Something to keep in mind after you pass your test is that you're not done yet. The rest of the codebook is yet to (never) be conquered. After decades of electrical work, if you decide to stay, you'll still learn something new every day.

This is a good forum to learn a lot from just by visiting every few days and reading the post here. Another place to try is electrician.com, and the Tom Henry series is also pretty good. There are others out there. As stated above, the first three chapters and part of four are a good place to start. But for me, I took Code classes at my local technical college. I would check there for classes and books that have questions for study. Good Luck.
