I personally was given a place on Animal Behaviour Science even though I missed by 20points I believe.... and even thought I had already been accepted an acceptance letter..I was at school so didnt know.. so called up and the lady I talked to was part of the agricultural center, and seemed impressed by my GCSE grades, my telephone voice, and my Personal Reference....and actually gave me an ADDITIONAL place for that same course..as we both didnt know Id already been accepted xP
you just gotta hope you set yourself up for success earlier... I suggest calling main office and then asking to speak to admissions for the course area you're hoping to enter..... hopefully you'll impress them.
