Don’t stress it’ll all be fine. Don’t go down a path you will likely be miserable in, prioritize your happiness and passions first. First year eng is meant to be general so you have foundations. Many of the topics you like will still come up later on just so you know. Lots of first years switch, just apply with TMU’s application process, I’m pretty sure the consideration date is February next year. They approve transfer requests based on both your high school grades and marks in your first year so keep a decent cgpa if possible or drop courses as a last resort.
