I'm more confident that the exam is tricky and not difficult, and you're better off getting 10 hours of sleep before the exam otherwise you'll drift off and make stupid, stupid - harmonic<geometric<arithmetic - stupid, stupid mistakes!!
I left the exam thinking I scored about 75 percent overall - with about 40 questions I knew I got wrong afterwards. Then another 20, I had a bad feeling about. Now I'm thinking about 70 percent after reading posts that suggest that I got another 10 wrong which may have been out of the 20. So I'd say I'm between 70 to 75.
