Directions: This exam is open book, open calculator, and closed notes. All questions are worth 5 points each so if you get stuck on a problem, move on and come back to it later. Although there are 21 questions in all, you only need to answer 20 of them. Any extra questions you answer will be counted as extra-credit if you get them right (up to a maximum score of 100). You will be allowed the entire two hours to finish this exam so take your time. Just settle back into your chair, take a deep breath, and relax... Best of luck!

• All questions are worth the same number of points so do the easy ones first!
• If you get stuck on a problem, find a problem similar to that one in the homework set.
• Don't leave any problems blank! Put something down for each problem so you can at least shoot for the partial-credit.
