NACLO

The North American Computational Linguistics Olympiad will take place on Thursday, January 31, 2013.  Interested students should register at:  http://www.naclo.cs.cmu.edu/reg_student.php 

Last year Milwaukee had the second highest number of students compete in NACLO, coming in after Carnegie Mellon University where the competition began.

I also recommend googling "NACLO Sample Problems" to print out problems from the last few years of competition.  (The answer keys are available, too--phew!)
