Oh wow that is good to know. I might just have to give it a test run for $10 and see if I can handle it in one go. I know they don't tell you your score, but how did you feel about the 160 that you did answer? Even if you assume you got 90% of your 160 correct, that's 144/200 = 72% . So you must have done pretty well on the ones you answered! Or perhaps it does some sort of special calculation for questions that you miss but ran out of time to complete. Perhaps they only count half off or something?
