Once, Kintergarden believe it or not. I passed all the actual knowledge needed to move on. They just thought i'd be "disruptive to first grade."
If they'd bothered to find out why I was disruptive they'd of known it was due to the fact that I already knew how to read, write, add subtract and multiply... my parents taught me how to do all four before i was even enrolled.
Kinda hard to sit though days of "This is A.. it makes an ah sound."
