Ha. Same test thing happened to my dad in the UK when he was called up for selective service. Handled the easy test in 5 minutes, but he was told he had to wait until everyone was done. He said the questions were like: Which is the odd one out- square, circle, triangle, elephant. And he said an hour later, there were still people trying to finish in confused frustration.

My dad got out of service entirely. He would never tell me how.
