Benefits of participating in a CEMC contest
CEMC contests help participants:
- discover and grow a love of mathematics and computing,
- foster creative problem-solving, critical thinking, and analytical skills, and
- learn about new concepts to make connections across topics in mathematics and computing.
Since CEMC contests are challenging yet achievable activities for young learners, they also build students' confidence in their ability to tackle difficult problems — a key ingredient for student success both inside and outside the classroom.
