dw u didnt miss out on all that much. They gave us an on-campus tour showing us where all the important places are like the Co-op bookstore, library, MULS office, bar and various rooms. They gave a presentation that offered a pretty good snapshot of what Macquarie student life is all about, re-iterating the usual snuffus about the importance of making friends, having a social life etc...
The most important thing they mentioned on the day is that Law camp is on from 18-20th March so be sure to buy tickets early, during the 1st week as they go really quickly and there are limited places. It was more about the on campus tour than anything else really. And if u want more info then the Macquarie Law Society (MULS) and mentors have a facebook page so check that out.
