I recently took the same exam as well, and felt the time was too short. I have a methodical process for answering exam questions that has left me with several minutes left over on previous exams, but this time I had to rush the last few questions and had no time to go back to take a second look questions I wanted to look at again. As usual there was also a question that was a little ambiguous and had a different correct answer depending on how the question was interpreted.
