i believe ONLY unsw sends out interview offers before you actually get your umat marks.
so don't worry if u don't hear from any other unis- you're not supposed to.
(btw, it's almost the end of september, so make sure u get your uac, vtac, qtac, utas, satac, tisc applications in
and any direct applications 2 the uni that u need 2 do... make sure u've done them and u have sent them off by their due dates.
check the faculty of med websites for each of the universities ur applying 2 just 2 doublecheck
)
