How hard is it to get into Queen's University?

I REALLLLLLLY want to go to queen's. But I have been having a bad year. I just got my first semester report card back and I only have an 84% average. However, I am hoping my second semester marks will be high and pull it up at mid-terms so maybe they will accept me in final rounds? Ahhhh i have no idea! But i applied for psychology and I am hoping to make my personal statement of experience really good. HOPEFULLY!. Somebody said it was only like 82% to get into poly/sci, but that the average overall was 87%. What's it for psych? HELP! I am freaking out! Any tips for the PSE would also be greatly appreciated.
