Gifted but young for college

Here is what https://sfs.virginia.edu/sites/sfs.virginia.edu/files/FAQs-125%25SurchargeRule.pdf says:

In other words, someone bringing credit from high school dual enrollment, AP, IB, etc. when starting as a frosh as UVA can exclude that credit from the 125% threshold. That means that s/he can take a full four years of full course loads at UVA without having to pay the surcharge for going over the 125% threshold. Or at least that is what this document says.
