I'm confused as well. Yeah, there are a lot of duplicate questions, but if you drop out the 1900 (why would you drop out the 72 performance, if I recall, I had quite a few of those on mine), 135 section, and some of the other easy stuff, that cuts out quite a few. Besides, buy the book for whatever it costs these days, read the sections you need a couple times, and boom, ready for the test while saving $300. Can't believe somebody would pay $300 to read out of a book.
