This exam had three free-response questions in 60 minutes (a 10 minute reading period and 50 minutes of writing), with a suggestion to spend about half the time on Question 1 and split 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.
