We work every weekday evening and this means generally 4pm to 8pm. We can work earlier (sometimes students have no lessons in an afternoon). We can do weekends by negotiation but prefer weekdays.
At the start of the academic year there are plenty of gaps but as September moves to November we get fuller. We start work any time you need us but it just gets harder to find mutually convenient slots.
Note that we require a parent to be at home when we teach.
