Summer and Winter Sessions

MCC offers a wide range of credit courses during the summer and winter intersessions. Credits can be applied to a degree or certificate at MCC or transferred to another college or university.

What You Need to Know about Winter and Summer Courses

If you are registering to take a credit course and are not currently enrolled in classes at MCC, complete an application for admission. Students currently enrolled at another CT Community College must complete an application to activate their Student ID on our campus. Current MCC students do not need to complete an application to register for intersession courses.

Special Note: If you are attending another college or university and intend to transfer your MCC course(s) to your home institution, please check first that these credits are transferable to your school. There are no refunds past the allowable drop period, whether a course is transferable or not.
