It also proved how tough teaching can be be, and the tremendous achievements of Britain’s 'Dream Teachers'. And now Jamie Oliver and YouTube have announced the seven winners (see videos below) of the programme's national video competition to find answers from teachers to the toughest topics at GCSE and Standard Grade.
