Eighteen. But I plead cultural prejudice - I would have gotten the two Canadian questions right.
I give the tester about fourteen for his/her questions. The other eleven are too ambigious or make too many assumptions about "standards".
And what about the obsession with cheating? I was witing the answers down
with a pencil, so it was kind of hard not to cheat on that one. As for the letters on the phone dial - I have a phone right on my desk with
no letters on it, so cheating wouldn't help.
If I was going to cheat, I would have just claimed 24 and gone into a tirade about cultural prejudice.
People who think they have all the answers usually don't understand the questions.
