What Students Say About Online Classes
“I was very reluctant to take online classes, but because of my various roles as a wife, mother, full-time employee, and student my time was limited…. Online classes have helped with managing my time in these various roles, and have been a true blessing to both my family and my learning experience at WCC.”—F. Robertson
