A Key will be posted by the end of the day Wednesday. Please DO NOT email asking for one any earlier than that. You should study BEFORE you take the practice. If you have studied sufficiently, you should be aware of the validity of your answers on these questions. If you are unsure of any answers, use that information to go back and look into those topics again. Finding the correct answers for yourself will contribute more to your studies than just looking them up on a key. Knowing whether you have the correct answers is a good measure of how well you have studied. A word of CAUTION: DO NOT use the practice to narrow the material for study. Any exam can only be a spot check of the material we covered in over five weeks of class. Also, there are no graphics on this practice. There may or may not be graphics on the exam.
