Well the subject hasn't started yet but I'll briefly run through the process:
You can get an enrollment application form next year in September or so for 2011 subjects.
Fill that out, submit your reports for Semester 1 and Semester 2 by mid December then wait until this time next year for the approval of your application.
Then attend Welcome Day like we did last week

.
And then start the actual studies in February or March at either a host school or the University itself depending on the subject.
Hope that helps!
