Whether or not this is true depends greatly on where the individual lives, and how big their school was. I knew someone in high school who was in my grade, but was two years younger (meaning he was skipped up two grades), and he had no problems.
Not only that, but whether or not the person could keep up academically would depend on them, not how old they are. If they really are intelligent enough, and they apply themselves, they should have no problems.
