I, and probably many other people, would do a lot better in life if scantron was used beyond big state colleges and into real life.
Imagine your work days, finishing the scantron test in about 30% of the alloted time, getting paid in the 99th percentile as per your score, and being back home by 1pm....
As a bonus, no one would do worse than 20% of perfect, which anyone could attain by random choice.
Then, of course, there would be the smart/stupid people, who would get a score lower than what you would get by chance, because they had all the answers correct, but put the answer for question 2 on row 1, and so on...
This happens because people design tests, and don't like to repeat letters for correct answers. So if you transpose answers by one, you are likely to score less than 20% (assuming standard A-E scantron forms.)
