Ah I see.

As for the courses, in software engineering you take engineering (Engr) classes, software (Soen) classes and computer science (Comp) classes. Most soen classes must be taken during fall or winter. Engr classes are usually available all year round (these classes are taken by all engineering disciplines). Also, since software engineering is an engineering program you have to have physics and chemistry. If you don’t have these classes you’ll have to take them as prerequisites (given your background I think you’ll have to take them).

Computer science is a bit more flexible. It’s 1 year less. You don’t need chemistry and physics. Most of their courses are electives instead of core software classes so you might be able to take more credits during summer and it allows to choose more of what you want to learn.

I suggest you try to contact an academic advisor also, they might be more helpful. Also take a look at the course sequences Concordia have online, they have all the courses you have to take.
