I think you'll be fine, if you're going to be heading there when it officially starts, so before 9:30, you'll be with the office opening hour crowd, so it will be fine :)
there is a meat on Tuesday next week at USYD, it's a study meat and there will be two seminars, one that is maths related and another that is to be decided :)
I'm considering to go, but then again I didn't get to go to the English seminar. I still reckon it would be useful, as she might have thought of new ways and tips to apply. And going again would also reiterate the info from the last seminar? :)
