Mathlinks (http://www.mathlinks.ro/index.php) is one of the best resources for high school students who are Maths Olympiad enthusiasts. You can find past year questions, answers, and forum discussions on all sorts of Maths competitions, such as IMO, APMO, AMC, USAMO as well as local Maths olympiads held within different countries.
My favourite is the following thread:
Forum » Olympiad Section » Geometry » Geometry Unsolved Problems
