OMG! I cannot believe somebody has found it easy! I have been trying to find a volunteer role for more than a month. Some schools haven't even bothered to take my cover letter; most of them have not bothered to reply to me and in one in particular, they were really really rude to me! For what people mention, they went to the schools they used to study as children first. Maybe that is the problem - I have recently moved to the UK and I don't have the local connections!
