The issue with the reading materials often times becomes memorization rather than truly understanding the theories, or knowing how LAs practice. I passed Section 1 and 2 relying on the reading materials and personal experience. At this point, I don't remember anything I read for the exams, but I continue to retain the knowledge from work, if I don't know something, I grab the reference materials! (Which is why it kind of bothers me that the Graphic Standards -- a reference book, is a recommended reading.)
I understand it's hard coming up with an exam that would please everyone (you can't), and they are trying to get us onto a certain path (Project Manager, Master Planning, Construction Document, etc.) of Landscape Architecture when in reality, there are so many subsets of LA that many of us won't even get into.
Part of my personal struggle is to get myself out of the specialty that I had gotten myself into and try to look at everything from a "high-level" in order to pass my exams. But because the exam is the way it is (trying to remain high level and yet trying to get into the weeds on a number of topics), I need to juggle with not letting what I know in details to get in the ways of "high-level" materials.
I think overall, if they are suggesting some study materials -- the exams should reflect more of those study materials, or offer more us updated materials to study on. Or, actually test us on actual experience/how LAs actually practice! It's an expensive process and it's absolutely soul crushing for people to fail them and then having to retake.
