If you log in with your UAC info 6 hours after accepting your offer, you should be able to access 'student login details' under 'my admissions'. You'll need to activate your account with the info there (student no./program code/DOB). System seems to be taking much longer than usual though as mine hasn't registered yet, although it might be a bit different as I'm a past student.
Oh okay awesome I’ll try that and see if they’ve registered me yet then, thanks!
