The treasurer takes care of one of the most important aspects of the assocation: its finances! You do this through accounting and keeping the books. You also assist committee members with the financial side of the projects. Because the treasurer has a crucial view on the current financial situation, you are important in determining the assocation’s year policy. You are also constantly updated in the financials of the projects and thus are the go-to guy for the president to see how the projects are coming along.
You are also reponsible for the book sale each block. If you like being involved financially, this function might be something for you. Just remember that this function also carries one of the biggest responsibilities!
