Thursday.
A student in another country completes the online placement test her agent sent her; the objective sections are scored at once, a teacher marks her writing sample on Friday morning and confirms upper-intermediate.
The registrar enrols her on twelve weeks of general English, intensive, starting in ten days, with a host-family request for the same dates.
The agent sees the booking appear in his account.
The accommodation officer matches her to a family with a room free for exactly those weeks and the arrival details go to the student and the family.
