Thursday is the final day to vote in the White House's commencement challenge. Kalamazoo Central High School is one of six high schools across the country in the running to have President Obama speak at commencement. Wednesday K-Central students and other supporters were urging motorists on Kalamazoo's west side to vote.

Videos from Kalamazoo Central and the five other schools are posted on the White House website, and can be rated on a scale of one to five. The videos that finish in the top three of the voting will be considered to have President Obama speak at commencement. Voting continues until 11:59 Thursday night.
