Do ivy league colleges such as Harvard and Princeton accept students who are enrolled part-time in high school and part-time in a community college their senior year?

I know not about Hahvahd or Princeton, but I know that Yale does admit students who are enrolled in early honors type programs who have taken community college courses to supplement their high school education, or to take courses not offered at their high schools. It is, however, somewhat difficult to get college credits from the community college courses to count towards your Yale degree if the community college courses were taken during high school. I think it would be valid to assume that Harvard, Princeton, and the other five Ivies have similar policies.
