This was amazing. Didn't like it at first, but as the year went on, I started to become more interested in history. I know that this is a boring class at times, but what you'll realize by the end of the year is 'wow, this class was better than expected, and now it's over'. I'm finishing up my junior year and wish I could go back to experience some of the moments again, because I didn't pay attention. You hate it one moment but then you start to love it the next, but by that time the course is over and you wish to experience it again and don't want it to be over.
