I don't know if they are sessions in all unis but for mac, what do you mean by session 1 and session 2? When u r enrolling in units on the e student website.
e.g. 2014, session 1, North Ryde, Day & Evn
Any ideas? ty
Session is simply another word for semester in this case.
Session 1/Autumn Session etc. means the first half of the year
Session 2/ Spring session etc. means the second half of the year.
If you see session 3, it either is referring to summer classes or your looking at the city campus timetable (as they have trimesters rather than semesters!)
