The California Informatics Competition (CALICO) is a semiannual team programming contest organized by students at the University of California, Berkeley. We create original problems to encourage students to grow their problem-solving skills and learn algorithms in fun and exciting ways.

The contest will be **2.5 hours long** and you can compete **solo or in a team of up to 3**. There will be **around 8 problems** spanning a wide range of difficulty **for all skill levels**. Some problems will have **bonus test sets**, where more efficient or advanced solutions can earn additional points. At least one of the problems will be **interactive**. **Anyone can compete** in the contest, but **only pre-college teams will be eligible to win prizes**. **Editorials for each problem will also be available** after the contest. More details will be released as the contest date approaches.↵
