Ratio calculated against the coming year's places — the notice does not state a comparable figure for last year, so this compares two school years.
Read this one with care. The notice gives last year's applications but not last year's places, so this divides them into the coming year's intake. If the school has grown or shrunk, the real figure is lower or higher than this.
