Why an empty field is better than a filled one
It would be trivial to copy an item count from another site, and you would have no way to tell we had done it. On an exam you pay to sit and that is mid-reform, a confident wrong number is worse than an admitted gap: it makes you plan a pace for a paper that may not have that shape. So the fields we could not verify say "not published" and link to the awarding body instead.
What we can say for this level is what holds across levels 1–6 generally: the exam sold and sat today is the legacy six-level format, with Listening, Reading and Writing, and reading as one of three reported scores in the points total. For anything more specific, pull the official level page before you plan.
