Go back to the Graduate Seminar sheet. Essentially, you will have 48 minutes per question. Be sure to stay faithful to that time frame. The place where most students have difficulty with this exam is in time management. Use a few minutes to write down your outline and a few minutes to proof read.
Most students tend to answer the question that they are most secure with first.
Then wait and answer the question that they have the most difficulty with last. This is a bad idea. I suggest you write the toughest question first and stay faithful to the 48-minute time frame. Then move on to the next question. Eventually, you will get to the question that you feel most comfortable with and will probably be able to answer it in 20 to 30 minutes.
