I'm in the comp sci program and my 1FC3 mark isn't amazing to say the least. I'm really trying not to fail it but what happens if I do? It is required to have a complete on it for all my level 2 choices, and when I checked it's not available in summer school. Obviously failing this course will not allow me to continue onto level 2 but since it's not available in summer school what do I do? Do I just wait for it to come around second semester of next year (the only time it's available) and only take it again all by itself? Or can I just take all the second year courses for my program that don't require 1FC3 and reapply next year after passing? Just kinda confused. Any help is welcome.

You should talk to the academic advisors for your program. I had the same problem with a mandatory course for my class; I didn't fail it but I had just been unable to take it by the time I was supposed to. They waived it on the basis that I would take it in the future.
