A US kid who hates school but has above-average general intelligence (so, not the prodigies who teach themselves Attic Greek at age 6 and go to Harvard at 12, just normal 1-in-50 or 1-in-25 smart kids) can probably bail on high school when they're 16, get into a community college (test scores ought to do it), take all the courses for an associate's degree, then snag a GED when eligible and officially pick up the degree. Doing all that plus having a part-time job is almost certainly a smaller time commitment than high school is and you'll get basically the same education or somewhat better, except you'll already have a degree and a ton of transferable credit toward a bachelor's at age 18.
