The Final is growing closer

So for par of our final exam we have to define terms in a few sentences. this whole final study guide has have all the questions on it, i am really suprised! It seems like a trick or something, because my instructor has been fairly hard all semister but know is letting us know the questons before the exam! It kind of blows my mind! So naturally im assuming its a trick of some sort. Mabye the final is scored like golf, the lowest score is the best, and everyone will prepare alot and score alot of points, but in reality that is lowering their grade. I know it sounds crazy but thats the only explaination.
