How Many other people will be on the course?
We always run our courses with small groups, and often turn people away if the course is 'full.' Our maximum group size depends on a number of factors including the room size and layout, but we usually have a maximum of 10 - 12 people on the course - frequently fewer. We never have a group so big that there isn't time to answer everybody's questions, or space to cope with the practical sessions.
