Time flies and it only seems like yesterday since all of these pupils were in Year 10 and 11, from Pennywell to Thornhill and Seaham to Biddick.
See if you can recognise the celebrity cook in the picture at Thornhill in 2014 or the TV personality in Seaham in 2012.
Top marks if you get in touch to tell us more.
