2010, Form B, Question 3 · 5 points

This exam had three free-response questions with 10 minutes of planning and 50 minutes of writing, and the directions suggested spending about half the time on Question 1 and splitting the rest evenly between Questions 2 and 3. The current exam has 3 free-response questions in 60 minutes. The skills these questions practice still count.
