Don't write anything sucky about the college in case you get pooled...
...actually, you will not get pooled if you apply to St Hilda's, so you can if you want. But it will not have any affect.
Basically, leave it blank if you have got nothing in particular to say, and leaving it blank will not bother you.
If the idea of leaving it blank does bother you, then sure, write something. Talk about your Bac if you want. But really it will not be the deciding factor about getting an interview.
If universities do not know enough about your qualification, perhaps you should give Hilda's admissions office a call and explain it?
