Chris Enwright of Ellowes Hall secondary school in Dudley, West Midlands, wins this week's Dubble bars for his twilight GCSE applied ICT group. "They turn up every Friday after school voluntarily - they want to be there," he says. "And regardless of how my week has gone, they cheer me up. They're a credit to the school." If your class deserves a treat, email email@example.com to tell us why, giving the name of your school and marking your message Dubble offer. For information on fair trade, go to www.dubble.co.uk.
