The Oxford German Olympiad is a national competition for pupils learning German.
There's a choice of tasks for each Key Stage, and an open competition for groups of 4 or more, with a deadline in March. There'll be house points for everyone who takes part and, ultimately, a prize-giving ceremony in Oxford in the summer.
See the attached PDF for more information. If you're interested, come to a meeting in K12 at 1pm on Monday 12th December. (German Christmas biscuits provided!)
