Saw this post from a former CTY (gifted) kid who claims he took caffeine pills and got a 1590. I'm honestly considering letting my kid do it given that they have ADHD and caffeine helps them focus. I think it's safer than coffee because you can know the exact dose, and it would just be one time for the test (and maybe one time before the test to see how he reacts). Okay, I know it sounds bad, but would you honestly do it if it could help improve your kid's test score by say 200-300 SAT points?
