Mathematical Excalibur (pdf)

In 1994, the International Mathematical Olympiad (IMO) was held in Hong Kong. In January of that year, we began to post a math newsletter called Mathematical Excalibur on our department webpage. You can find all the issues up to now in the box below. 

In each issue, you can find a math olympiad paper, an article or two on math olympiad topics and a problem corner. Over the years, we received many contributions from readers all over the world.
