re: ACT scores are horse sh*t

The ACT/SAT's can't measure a lot of things that factor into school/real world success, such as work ethic, organization, creativity, people skills, ambition, etc. However, from a pure "book smart" perspective, i.e. the ability to absorb/analyze information quickly and correctly, as well as command of the English language and mathematical skills, standardized tests are extremely accurate in my experience. Pretty much everyone I know scored on a proportional level to how purely book smart they were.
