I'll start...
At the end of my junior year of high school, I found out that I was qualified to take AP Government during my senior year, so I went ahead and signed up for APGOV. We were given a list of about 20 books from which we had to pick five to read over the summer. Well...
I actually did get a head start on checking out the books on the list, just to see what I thought would make for some "good summer reading". Well, none of the books were "good summer reading". And, of course, most of them were over 300 pages long. -Who knew that so much could be written about the U.S. Government?

Well...
I believe I managed to get through 1/4 of one of the books, while the rest sat more or less unopened on my desk. Needless to say, it came as quite the shock when we were suddenly handed pop-quizzes - well, more like pop-tests - about the books we were supposed to have read over the summer during the second week of class. I somehow managed to scrape by - as did a number of my fellow AP Government classmates.
*Worst of all - unlike the AP English reading list (which I did like, and which I did read (more or less)) - we never referred nor used any of the texts from the AP Government summer reading list during the course of the course. Yes, we covered the related topics, but our text book remained our only text for the class.
