They don't really waste your time. There's a short (hour long) orientation that you get paid your usual rate to attend, and then you're give the teaching materials, given a schedule, you teach at those times, and then money arrives in your mail every few weeks. You do need to write a quick summary after each session, but that shouldn't take long. You're given a lot of independence. That can be a bit scary, but it's also kind of a relief. Management is fairly responsive, and seemed understanding when I couldn't teach a course. I think they were pretty willing to listen. They did a review session at the end of my work there to listen to what I had to say and get my input on various aspects of the job/course, and that review session was paid as well.

The work itself deals with trying to teach children between middle and high school. How good or bad that is depends on you. I found the older kids were eager to learn, but the younger kids were sometimes easily distracted and patience is needed. They only pay you for the hour/two hours a day you spend teaching. Not any of the time you spend preparing the lesson. How fast you are at preparing a lesson is up to you as well. I should note though, they do give you a lot of material you can use to teach, and for a lot of the classes, the projects came with finished versions, making preparations easy. Still though, don't expect this job to only be an hour/2 hours per day of work. Speaking of which, you won't be working that many hours a week with this job. 5-10 hour weeks are common, out of the 12 weeks I worked there was only two 20 hour weeks. That was fine for me, but obviously this is not true for everyone.
