Reminds me of when I applied to be a cop at the local PD right after high school. They sent me a thick, 10x8" booklet, and clearly stated in the accompanying letter that the entire test would be based on what's contained in it. So I spent the summer literally memorizing every word till I could practically recite it cover to cover. As a result, my score all but topped out the test, and I was immediately told that I'd be in the first group to continue along the hiring process, and that I should get a gym bag, sneakers, shorts, etc.. in preparation.
A week later I got a notice stating that the hiring process had been halted by a judge based on a blacks rights organization lawsuit (very few if any of those with high enough scores were black). Next letter I got from the police department told me that, due to the test having been deemed racially discriminatory, a judge has given my test score to a low scoring black applicant, and I'd be taking his low score, meaning I would not be hired.
This was the early 1980s, so this crap isn't new. They've just now decided to get rid of the tests entirely, due to their tendency to discriminate against blacks.
