How much how often?
£40.00 per hour
I often recommend booking two hour sessions in order to get through a large amount of work in as much detail as you require.
Private tuition is very flexible. I suggest booking sessions as you need them. People are often surprised at how much can be achieved during a private tuition session and so you may not need as many sessions as you think, and you may not need them as often as you would classroom tuition perhaps.
