Registration week 15 to 19 September 2008
Although be aware, some/most courses will have reading weeks amongst all that where you don't have classes....and the law school in particular seemed this year to invent their own term dates where we would finish a week or so earlier at christmas etc than other schools.
And i'm home now so whilst June may be the 'official' end of semester 3 date, you're done when your exams are done and this year, first year law exams were done last week before most other schools had even started!!
