i tailored mine for schools where i thought it was relevant. for instance, a lot of strengths that UBC has are things that i am passionate about, so it seemed natural. whereas at OZ, there is absolutely nothing that i could say about that school that would sound sincere. if you can try to tie it in, i think it would be great. plus, it shows that you have taken the time to research the school and are genuinely interested in something unique about its program.
