thank you all for your answers, its a per month charge and also i take that time away from my kids and spend with the student so i was wondering if the fee is fair.
yes i enjoy teaching and i agree its a privilege but i always encourage the non working parent to spend time teaching their kids at home, but some parents choose to outsource it as that is then their 'free time'
having seen all this i want to be compensated fairly, thereby the question.
