Of approximately 30 teams competing, Sachem North earned both 1st and 2nd place in Suffolk County! The amount of time and effort these students put into preparing for the competition is very impressive. The 1st place team members each won $500 and all expenses paid to compete in the NY State competition at William Hobart Smith College on Seneca Lake May 24th-25th. We wish them the best of luck in next week's competition.
