Please be warned that the list may contain observers who are not necessarily officially registered or eligible for prizes. If you are an eligible high school student and you've registered on [url]http://woburnchallenge.com/register[/url], then your rank at any given moment may be higher than it actually appears!

As a final reminder, you are allowed to read and submit to the problems from both of the divisions. So if you are finding this division too easy, feel free to exit the contest and enter to senior contest to peruse the problems. However, if you submit to both divisions, we will only count your submissions in the higher division for prizes.

Good luck!
