What about time?

Generally, you have about 3 hours to take either exam. This corresponds to about 60 questions per hour (or one question per minute) that should be answered in order to finish in the allotted time. Some questions will require a little more thought and thus a little more time. Other questions will require less of your time. The bottom line is that you will have about 3 hours to take the exam. This should be plenty of time. In fact, for some students this may be too much time because it allows them to go back and change answers. Statistically, your odds of changing a response to a correct answer are lower than the reverse. In other words, your first impression about an answer is usually correct and if you change it, you're more likely to change it to an incorrect answer. Stick with your first impression!
