I only applied to UofT last year and was waitlisted so I just spent the last year trying to really improve my application! Even though I didn't apply to UofT again, I definitely think that my application to other schools is much stronger this year (although I'm still waiting on York which is my dream school so fingers crossed!). Originally I was going to go back and do a fifth year to try and boost my GPA but then ended up getting accepted to an MA program last minute- which I honestly think is a lot of what schools like about me, that I already have a Masters going in. Also, considering that GPAs in MA programs tend to be much higher it also boosted my application in that regard. In terms of experience between the application seasons, over the summer I volunteered at a camp for underprivileged youth where I got around 1500 hours. Other than that I have been really involved with social justice work at my university, and have worked with a few NGOs in overseas in social justice work. I think I have around 3700 hours total including this last summer. Also I know that my written statement was much better this year- last year I was very general and vague whereas this year I focused in very specifically on my current research question and how I wanted to expand upon it using a social work background. I hope that helps! I was so close to giving up on the whole thing after last year and am so so happy that I kept working at it. Don't get discouraged!
