Gap in experience effect on admissions?

hi guys! im in my 3rd year at UofT and will be applying to teachers colleges in fall of 2025. I am a little behind in my credits, and still want to graduate by spring of 2026, so I am thinking about not joining any extracurriculars next year, and instead focusing 100% of my energy into school so I can take a heavier course load and graduate on time. I have a lot of experience hours already (will have 2000+ by sept 2025) but Im wondering if it will look bad if i dont have any experience in my 4th year of uni. what do u guys think?
