I didn't have any contact with the online 'teachers'. I could contact them, but I just didn't bother. I didn't do any assignments either. I started out with a 'testfase' to see if you're up for it which lasted half a year. I got trough half of the first book (out of 3 from the test fase) and I just stopped working on it. But you should work next to it. An online study isn't meant as a full time thing, but part time. You were ought to spend about 20 hours a week on it, then you have got a lot of spare time where you can't do much, you'll get bored pretty quick. I had a 40 hour contract, so I couldn't combine it. But if you work 20 hours a week or something in a store it shouldn't be too hard.
