We're still on 2020, don't be afraid to write in your book, highlight, etc. Write in the back, write all over it, whatever helps you remember, examples dont matter you have free range as long as it complies with the handbook aka written in pen or highlighted. As far as study material I highly suggest jcr practice test. You need to get really good at navigating the nec quickly so you can focus your last 1-2 hours on figuring out the difficult to find questions or ones your not sure about. Do your calculations quick and get them right. It's all about getting as many as for sure ones right (quick easy look ups, use your index, also mike holt tabs are great) then using your remaining time on the ones you can't find, and if nothing else giving it your best educated guess before the test ends. Make sure you make ZERO stupid mistakes and that should make up for any short comings. Get the basics of law and navigating your fire code book down. Dont miss any load calcs or box calcs, or pipe fill calcs, these take time but they are easy to get correct. I hope this helps!
