So it's a 6 hour test, broken down into two 3-hour sessions. What happens if you get done with the first part well before the first 3 hours? Do you have to just sit there for a couple hours twiddling your thumbs, or can you start part 2 early? These 125 practice tests only take about an hour or so. I'm sure I'll be more cautious on the real test, but I'd like to make plans for tomorrow's test if I know whether I can be home by lunchtime.
