Actually, might not have to studied much.
I just finished my masters but I passed the Electrical PE with an 88 only having looked at the NEC for a couple of days. If I had taken a prep course like Testmasters or whatever, a score in the 90's would have been pretty easy. I probably would have...
88 Power. Happy to pass but had I studied more than 20-30 hours I could have gotten into the 90s. I would have liked to have beat my boss's score so I wouldn't have to hear about it all the time.
