The California Informatics Competition is a high-school programming competition hosted by students at UC Berkeley. We create contest problems to promote the understanding of useful algorithms and encourage students to grow their problem-solving skills! To see some past problems, check out our Problem Bank.
What Do We Do?
CALICO
Our biannual programming competition is for students up to 12th grade. These contests are run during the fall and spring season, and consist of a large number of problems meant to be solved by teams. Come prepared to bring your best, and we will take care of the rest!
CALSUCO
Our CALSUCO summer contests are open to participants of all ages! Compete as an individual; these contests consist of multiple online, bite-sized rounds run during the summer months. Keep your skills fresh with these lower-stakes, casual contests!
Editor's Choice
These problems almost made the cut for our competitions--so close! These contests are released on our problem bank before CALICO competitions; no registration necessary! Same format, same rules--feel free to use these as practice material, tryouts for teams, or to test your computer setup!
Congratulations to the top contestants of CALSUCO '22!

FAQ
In short, anybody can participate! In longer terms, CALSUCO is open to all participants, regardless of age or schooling status!
Once you've registered, you can expect an email from us after the registration deadline about how to access the contest site. For more information on this, see "Contest Autograder Logistics" under our Contest Guide.
In the meantime, check out our "Preparing for the Contest" checklist, also found on our Contest Guide!
CALSUCO contests are meant to be more experimental than their spring and fall counterparts--they'll introduce new mechanics and ideas that you can expect to see soon at regular CALICO contests.
However, if you know how to work with conditions, loops, strings, and integers, you can start solving problems! At a higher level, our problems give students a preview into concepts taught at various classes within Berkeley's CS department. Regardless of whether you're just starting out or a seasoned programmer, there will be something for you!
All you need is a computer running an approved programming language, a text editor to work with, and a stable internet connection! For a list of approved programming languages, see "Approved Languages" under our Contest Guide.
Due to the smaller nature of the contest, participants will compete on an individual level.
The following prizes will be awarded to the highest-scoring individuals:
1st Place: $50 Amazon Gift Card
2nd Place: $30 Amazon Gift Card
3rd Place: $20 Amazon Gift Card
4th - 10th Place: $15 Amazon Gift Card
Amazon Gift Cards will be emailed to the winning individuals following the contest.
Check out our Contest Guide to learn about the rules, the structure of the contest, and other technical details!
Stay in the loop for CALICO announcements by signing up for email notifications! Our email list will only notify you when contest registrations open, along with other important updates.

Past contest problems, along with their full test cases and solutions, can be accessed here! We highly encourage you take a look. Practice problems will also be published here occasionally, so check back here every once in a while!
