The hourly wage looks great on face, but factoring in unpaid prep work (of which there is a ton) and unpaid commute time (usually around an hour of commuting for every two hours of teaching), you start to realize you're being paid absolute peanuts--probably less than minimum wage, actually. The work is also super unpredictable. Sometimes you have to fend potential new students off with a stick (they never expect you to take on more than you've specified, but they'll let you know when they're desperate), and other times you won't get any new assignments for months. It's impossible to actually sustain yourself on this job alone, but it's also very hard to make it work as a supplementary gig, because in order for the families to be happy working with you, you have to have tons and tons of flexibility, which you will not have while working multiple jobs.
