Mostly once a week. I sometimes have one family having me twice a week - and I felt bad they have to fork out so much. I also urged their 2 boys to work harder, do their own reading up more, instead of relying entirely on me - so as not to waste so much of their parents' money. (I don't mind the money if they are the Packers). Once a month is too far apart. But then again there may be students who are already quite good, but want the occassional guidance and coaching.
