What integrated scoring does to your prep
On a single-skill paper, a weak reading score tells you to read more. On PTE, it might tell you that, or it might be pointing at spelling, at grammar in a fill-in-the-blanks response, or at how quickly you work. The diagnosis is genuinely harder, and treating a PTE reading score like an IELTS reading band leads people to train the wrong thing for weeks.
Pearson also publishes the section as a duration range rather than a fixed length, and does not publish per-type item counts, so an exact rehearsal plan is not something anyone can build honestly from the official material. This page prints the range and the task types with their source, and stops there.
