What the awarding body publishes for this level
The official page gives the whole-exam item count, the approximate total duration including administration, the points total and the pass mark, and all of those are printed on this page with their source. What it does not give in retrievable form is the reading item count or a reading-only duration — its structure table renders client-side and did not extract during research. So this page says "not published" for those rather than repeating a figure from a study blog.
What is certain is that reading is one of three separately reported scores in the total. Whatever the exact item count, a weak reading result is directly visible on your certificate — it is not absorbed into a single number.
