Beast of a Handbook

I love reading, but I love reading something about history, or fiction books. A 71 page handbook about how to drive in the State of Utah isn't exactly my cup of tea, or in this case, my genre of book. There is so much information, and I have absolutely no idea what to study, or how hard to study. The only thing I know about the test is that there are three different versions. I don't know how many questions are on the test, and I don't know what the questions are on, I've heard that it's mostly just common sense, but I've also heard that it's a super hard test that you have to study for hours on end, before taking the test for the first time... HELP!!!
