I was a core French teacher for 20 years.
Core French is one course. We call it the drip-feed method; it's a little bit and that's why it's so slow and eventually so unsuccessful. I'm a product of that system. I came through core French, though Vancouver, but it was through many years of studying, cultural experiences, and living elsewhere.... As far as core French and your question go, no, it's one course within the program.
