eConcordia courses can be taken for credit even if you are not a student at Concordia University. As an independent student with Concordia, you can take any eConcordia course provided you meet the prerequisite requirements. You will, however, have to confirm ahead of time with your department that the course(s) meet the criteria for your program. You will also need to apply for authorization to have credits transferred to your school through the BCI website.
If you are a student receiving a grant for studies, please check your grant requirements in regards to online courses.
