Course Color
Courses will show in either Green, Blue, or Red.
Courses showing in red mean either you failed the class or the pre-/core requisites have not been fulfilled.
With a failed course, you can re-plan it for the future (follow the link for a guide).
A dark blue course means the classes were taken and passed. A lighter blue means the classes are currently in progress.
Courses shown in Green mean the classes are planned for future semesters and have no issues with planning.
