 Carson said other students walked out in protest when they discovered the retest was significantly harder than the original examination, but he alone finished the test.On doing so, Carson said he was congratulated by the course instructor who told him the retest was a hoax intended to find "the most honest student in the class".Carson said the professor awarded him $10, and that a photographer for the "Yale Daily News" was present to take his picture, which appeared in the student newspaper with a story about the experiment.
