In jurisdictions where there’s an exam required to graduate high school, let students of any age take the exam, but have a sufficiently higher cut-off to graduate early. Anyone who graduates early is automatically admitted to a university (e.g. in the U.S. it might be to their choice of state university) and received a tuition subsidy at least equal to the amount it would have cost the public school system to keep them in high school.

I remember fantasizing about this sort of thing in high school. Would have made my life sooo much better for a few years.
