Teachers upload their videos to a dedicated website. Students are asked to rate the lessons, to help identify which are the best. Each week, until 26 November, O2 Learn will award the most popular lesson a prize of £2000, to be split between the teacher and the school. At the end of the year, winners of the weekly awards will be entered for the O2 Annual Teaching Excellence Awards, where the first prize is £45,000.

At the end of 2011 the overall 1st prize was awarded to Sharmila Hanson from The Bishop Wand Church of England School in Sunbury-on-Thames. Her video lesson on rocket science teaches GCSE students about Newton's laws of motion. 

O2 Learn is 'building Britain's biggest classroom', allowing students from all over the world to connect to teaching from across the country. Gav Thompson, creator of O2 Learn, said, 'Through O2 Learn students will have free access at the click of a mouse to variety of lessons to help them learn in new and exciting ways that are most relevant to them.'
