If your child will be absent from class, we kindly ask that you notify us as soon as possible by contacting us at classes@cambridgemathcircle.org.

Absences without prior notice will be marked as 'unexcused.' Please note that students with two or more unexcused absences may no longer be able to continue attending the class.
