<p>My son started college-based math courses at 13 (he’s now 15). I’ve done all the enrollment and financials, he’s done all the academics. He’s very capable of doing the coursework, but contacting the instructor to question or contest a grade is pretty intimidating for a student his age. I’ll advise and coach him about how to address classroom issues, but I leave it to him to do it (or to decide not to do it).</p>
