In general, tutoring tends to be seasonal, with busy periods and not-quite-so-busy periods. Students and parents generally start contacting private teachers at the beginning of the school year in September then again in January, after prelim exams.
The quietest months tend to be over the summer holidays as students are quite relieved to have some time off after their final exams. It is possible for home educators to find themselves with students all year round if they advertise widely and make a good name for themselves in their local area. Often, over the summer months, many university students are keen to use the services of a tutor for proof reading essays.
