Congrats on taking it! I wish you a speedy exam grading process. I'm anxiously awaiting my written score from Nov.
Time management is difficult and people underestimate the need to practice it. 15-17 minutes seems like a long time but it really isn't for complex questions. The first time I practiced writing an answer, I only got about half of what I wanted to say written out. It was then a process of figuring out what info from my study guide I could leave out and what I thought would help improve my score. I learned that I can write about 1.5-2 full pages of text in about 15 minutes, so that helped guide my answer planning.
Mind sharing what your technical questions were? I'm always curious to hear what questions people got. If you read the study guide, you'll see that there is only the one possible style question. There used to be more, but they took it down to the one basic compare/contrast question during the last exam revision.
