I was going to suggest, as Benny did, to check into ADD as well. In girls, you won't always get the hyperactive body, but the mind tends to scatter. Not paying attention to details (taking a test before reading the directions), being easily frustrated and not hearing can also be a sign... if her hearing has been recently checked, and it's fine, she may be "tuning out" things due to daydreaming or having that "scattered" brain.
