its up to them to decide, because it depends on the calibre of your competition. SO jus tgo for it you have nothing to lose, and do your best in the upcoming exams. More likely than not you should get in if you have 90+ and credit average, i know a girl who was doing psych honours, low 90s, credit average, and got in comfortably i assume. Have a decent explanation written out, which might make the different if you are borderline.
