So im a first year student, and I passed matric with good marks.We recently moved into a new area and there are a bunch of schools here. I want to ask does anyone know how to let the people here know that we can provide tuition services. My sister is a University graduate and she’s willing to teach as well. The problem is we both dont have any prior experience of teaching children nor do we know how to get the parents to trust us for their children. Also if this somehow works, what should the fee be for specific subjects?
