There isn't a single answer to this question. Some people need one tutoring session while others need thirty or more over the semester. About 98% of my students are getting help with a standard-priced course and are coming to my home for tutoring sessions which reduces their cost. Typically a student will go for one hour, sometimes two in a single session. The total cost seems to vary from $25 to $600 for typical students. But I can say that the average student spends about $300 in a single semester with me. And this is significantly less than the tutoring sites that ask for $600 right up front.
