In about a year and a half I'm eligible to take my PE (Professional Engineer) exam.
It scares the pants off me. (Robin, no peeking!)
I actually need to talk to my bosses soon and see what they are willing to pay for/reimburse. I'm definitely going to be getting some giant books just like you, lol.
My plan will probably be to do a little bit each time. Once I really master one part, move to the next, but review the first every days to keep it fresh. Mix up where you study, when you study, how you study, otherwise you might get stuck in a rut (that's how I am anyway, other ppl are the opposite and have to study at hte same time, in the same place, etc).
It makes me wish I was still in college. I loved going to the Hub (sorta like a student union, but bigger) for hours on end. I could walk around when I needed it, get food (and caffeine!!), etc. People watch for a few minutes when I needed a short break. I'm gonna have to find a coffee house or something when it comes time for me to start......
Anyway, I'm rambling. But good luck! LOL!
