I was homeschooled from ages 8-19... would never send my kids to school. Ever.
It really is the best way to get educated - what I notice the most about my traditionally schooled friends is that they bow to peer pressure so easily... homeschooling teaches you to be independent from group opinions and cares. It also saves you from the crapness of the SA education system.
You have to go through exams to get a matric exemption, which usually entails AS or A levels in the final two years. You can sit them in a regular school - its easy enough.
Only downside is that you need to make a greater effort to have friends, but it isn't impossible.
