American Computer Science League Contests

There are 4 ACSL Contests spaced throughout the year. The first is usually in December, and the last is usually in April. The theory portions of the contest covers the following topics:

For a list of which categories will be tested during each contest, see the ACSL categories page.

At WMCI, we register in the Senior-3 division. This means that although each of our team members scores are ranked individually, we can qualify for the All-Star competition based on our top 3 student scores from each contest.


Any WMCI student may participate in any of the ACSL contests. All you need to do is to show up in room 219 at lunch on the date of the contest. However, note that without coming to our Wednesday lunch practice sessions, it will be difficult to do well.


There are 2 parts to the contest. The first part is a 30 minute theory quiz. There are 5 questions, and each question is marked as either right or wrong. No calculators are allowed!

The second part is a programming problem. You can use any language you want to solve it (most students use Python, C++ or Java). You have 72 hours to come up with a solution to the programming problem and submit it to Schellenberg. This section is also worth 5 marks, and is graded by passing in 5 test cases. You get one mark for each test case for which your code produces the correct output.
