I agree, but to get access to that arbitrarily designated college level work, one often must go to college, or at least use a curriculum that considers itself to be college-level.
Categories exist because people categorize things. That includes the people who create homeschooling materials.
BTW, I was not grade-accelerated in school, and I still found my first year of classes at a well-respected liberal arts college to be almost completely review. And that's after I tested out of most of the freshman course load, so even the sophomore stuff was pretty basic for me. I'm not entirely convinced that a kid will be challenged at college if he gets way ahead.
The best thing would be that a student could take more college classes, I think. I would have loved to have taken more courses than I got to take in college!
