To give you an idea of the organization and the types of questions that I ask on my exams, I have provided samples here from a previous class. Please note that your exams will be similar in style, but the difficulty (from your point of view) will most likely be higher. Additionally, your Concept Exams will have not have extra credit review questions.
The exams posted here are in pdf format. Most computers should have a program installed to open them. If your computer doesn't, you can download a free program called Adobe Reader from the Adobe web site.
