My kids got lots of AP credits, but they had no intention of graduating early. They used the “free space” in their schedules to add in classes “for interest” and for a couple of minors.
Some students do double majors, which can be a very good option if one of your major interests isn’t one that lends well to employment. So it can be a win/win…getting to major in a beloved subject, but also major in a subject that is more marketable. And if you’re really lucky, the combo can mean a career that includes both!
