It doesn't require it, but it does help frame the issue as to whether high school is a "waste of time."

For example, much as you describe, I scaled back my high school senior year to less than a half day in order to make time for community college courses. If I did not partially pull myself out of high school I would not have had enough time to pursue my education.

Looking back decades later I am pleased with my choice.
