I had a similar experience. I had studied while working full-time over the summer last year and I was resigned to re-taking based on my practice tests by September. I know many people re-take, but I had put in a considerable amount of work and was beating myself up over it. I ended up getting the score while sitting at an academic event and I ran to the nearest bathroom and locked myself in a stall then opened it. I felt immediate relief when I realized that my score was higher than I anticipated and that I wouldn't need to think about the LSAT ever again. Pure bliss.
I applied to Osgoode last year and at that point I had not taken the LSAT with accommodations and so I clicked no.
Now that I am reapplying for 2019, I am being faced with the dilemma of whether or not I should write that I have been granted accommodations on my LSAT.
Will this effect my chances if they know that I had accommodations and performed significantly better?
Windsor was the only school I applied to and I had a GPA substantially lower than yours. While I can in no way confirm this, I think that Windsor appreciated my decision to only apply there. I think it makes your stated interest in the school come across as more sincere. I think you definitely have healthy stats. Best of luck, hope to see you in the fall.
