Hello everyone!
As we approach the Massachusetts Computer Science Olympiad Summer 2025, we'd like to do
MACSO 2024 RECAP
The first Massachusetts Computer Science Olympiad (MACSO) was founded and organized by Mikhail Zhernevskii, Lucas Chen, and Tyler Sacharow, three Brookline High School students, in 2024. MACSO welcomed 278 participants from 182 schools in 40 countries to compete online and in person. The top 50 competitors from Massachusetts, Connecticut, Colorado, Pennsylvania, California, and even Canada came to Brookline to face off on October 19 at the Brookline Teen Center. MACSO became the largest high school coding competition in Massachusetts.
Over three hours, high school students solved 10 coding problems. Three MIT undergraduates Weiming Zhou, Thomas Liu, and Austin Geng solved the problems along with other students and kept the spirit of the competition. After careful review by guest judge Shruti Duhmak, a Google Engineer, the champions were announced:
