Actually, all costs considered, here's how it works out;
• Theoretical £128 / Month. However, this is closer to £96 as students miss a total of about 4 lessons a month. We'll call it 100 for simplicity's sake.
• 25% is paid to the School. That's £75 left.
• £50-70 is spent on medication. Averaged, that's 60. £15 left.
So, £15 left for me, which I have to use for general living, like buying food outside of School Meals and stuff. £15 = $22.81. So, I'm not actually making that much more than you.
Meh, it could have been, but I'm tougher than that.
