[b]Edit: The contest is over! Many thanks to all of you who participated. The questions have been cloned to the main judge. We will be posting prizewinners and analyses to all of the problems shortly. Check here, as well as our website periodically![/b]

[b]Edit 2: The contest problems have been posted to ([url=http://woburnchallenge.com/past-contests]woburnchallenge.com/past-contests[/url]) and also cloned to the main judge. Feel free to submit to them for practice while we work on publishing results and analyses. Note that J3 and S1 are the same question, so submissions to J3 are not moved over and junior competitors will have to resubmit them to S1 on the main judge.[/b]
