You have reached the evaluation server of the South African Programming Olympiad. If you were looking for more general information about the programming olympiad, you should visit the official web site. This site contains more technical information.
Any currently running contests will be hosted on the Contest Server, as well as a selection of past contests intended for preparation purposes.
The final round of the SAPO is a lot tougher than the previous rounds, and you will benefit from training. The best place to start training is on the USACO training pages.
You should also have a look at the previous problems, rules and environment to get an idea of what to expect.
A nice resource for keeping your competitive programming skills sharp is Codeforces, where 2-hour online contests are hosted more or less weekly.
