I know of 2 guys who passed the LEED exam by studying with a pirate copy that was missing 50 pages (single sided). They did not realize of the missing pages untill they passed the exam.
Goes to tell you how hard that exam is. You don't need a worshop for this one.
I prepared three times for the LEED exam, (one time with that pirate copy missing 50 pages), my problem is that I get mad at all the BS in that darn book, especially at the outraging exam fee. So I gave up taking it each time. I am probably a better LEED engineer by now than most LEED certified ones. My nature just won't let me take it.
In any event, if I were you, I'd study everything. Read the book three times, and it sinks perfectly.
Best of luck to you any way.
