Does your high school have a career class like mine?

My school has that as well, but they won't necessarily pay you and they won't provide you with transportation. People don't work during the school hours, though. It's not a mandatory course, but many people choose to take it because it allows them to gain a bit of experience in a field that they're interested in. Many past students have worked at law firms, dental clinics, etc. It's a common course nowadays.
