Can you give us a little more information about your situation? Are you a high school-aged person looking to attend high school via the internet instead of in person? I don't know of any internet high school, but home schooling may be an option. Depending on the area you live in an other factors, home schooling doesn't necessarily mean schooling done in your home. But then you'd have to worry about paying for materials. So you may still be stuck.
If, however, you're looking to go back to high school and are beyond the traditional high school age, you might want to consider the Job Core. It's been some years since I rode the bus regularly and saw the ads. But I seem to remember that they had a GED program you could get into in addition to learning a vocation. There may be other organizations in your area that offer similar programs. They would be worth looking into.
Again, it all depends on your situation.
