Students who managed to make it to university without the benefit of attending school have set up a group on Facebook. The group is called "Being home-educated didn't do me any harm - look at me now!" but a search for home education within Facebook will find it.
Sept '07
Just had a look and they are not all uni students on there, some are but they are part of as varied and colourful a group of great young people as you might meet at any home ed group nationwide It's great to see!
