I am confused what the course credits you mentioned here. Pls express it clearly.
Basically, there is no any credit for Intensive English Program (IEP) at the University of Ottawa. After taking IEP, you may need to take CANTest which is similar to the CAEL; then, university will consider accepting you according to your CANTest result.
special students don;t need any offer,you just need to pay money. for undergrads, u can only take up to 2 courses/semester, adn 4for those who already have a bachelor degree. Each faculties have different course requirement for special students, so check with your faculty advisor for more information
