My mom is a freelance music teacher. She finishes at 5.30pm so she can have dinner before seven. Her lessons take place during the week, she does not work weekends. Currently she teaches 8am to 5pm five days a week. On weekends, she likes to be on her deck relaxing, exercising in the gym or spending time with me and my little sister who is almost 6 now. It is always important to make time for family members.
Every year in September, she gives out a copy of her teaching/exam schedule. Hours when she teaches are green, hours when she is unavailable are red. Perhaps try that? She finds it cuts down on misunderstandings and mistakes are avoided. My mom has been a piano and music theory teacher, private since 2001. She is the only private piano teacher in her area so she is fully booked. Her price is £10 for lessons.
