The exam is what it's all about. It is your chance to receive college credit for your work all year. I won't lie, it isn't easy, but if you work hard all year you will be more than ready. I also recommend to stay as focused as possible when going through the review stages of the class. That is when you can learn everything you missed the first time. It all boils down to how much you put into the class. That's what determines the outcome of the exam. Do these things and you will pass the exam and save yourself a little moolah down the road in college.
