When I took GMAT 6 weeks ago, I opted to take the breaks. Since the test was 8AM-12 Noon, there were quite a few others taking tests at the test center. The lady that works at Prometric was too busy (because she was signing in others) to let me sign out and it caused me some nervousness. I tried to tell her the my break is only 5 min.. and she pretty much said- "well, you can't start again unless I log you in again anyway" ! While I was outside the room, the clock on my monitor screen was ticking, so didn't that mean it was being counted? How could Prometric be so insensitive?
