Question about applying to university

I’m currently on a gap year finishing the high-school courses I need for university. I’m taking 4 courses right now. I started 1 a few weeks ago, and I’m wondering if it’s still realistic to get into my program at TMU for Fall 2026 (Mechanical engineering). I know I’m cutting it close, but is it possible to apply even if the courses aren’t finished or far along yet? I can likely complete at least one or two assignments in each prerequisite by mid-December and then apply soon as I get my transcript.
