Mathematics & Computer Science Department

The Mathematics & Computer Science Department molds critical thinkers. With an integrated curriculum, new-age electives, and a healthy helping of blended learning, we are committed to providing innovative, student-centered courses. Within each course, students are encouraged to take risks and work collaboratively with a backdrop of significant individual support. Core classes are offered at every learner’s level, so all students will find classic Math concepts and their worldly applications truly accessible.


“Math pushes students to be imaginative, skeptical, and curious where they might otherwise settle for simple answers. Everyone wants them to grow as thinkers and problem solvers; this takes practice.”
