The written material questions
Two of the five subject areas are about written material, and the first of them is the only place in the whole guide where the Department publishes how many questions to expect.
Three separate test tasks, not one
The guide states that there are three separate test tasks in subject area 3, and gives each its own published count: Information Presentation From Notes in outline form, where a page of notes is typically followed by five questions; Information Presentation From Notes in sentence form, where there will be two questions; and Paragraph Organization, where there will be three.
The three are worth keeping apart when you practise, because they are different abilities. Dropping a fact when you turn notes into a narrative is not the same failure as putting four sentences in the wrong order, and a score that merges them tells you only that something in "written material" went wrong.
Paragraph Organization is decided by the sentences
Four sentences are shown out of sequence and you choose the arrangement that reads as one connected, well-organized paragraph. The order is not a matter of taste: a topic sentence refers to nothing earlier, and later sentences carry a reference, an enumerator or a sequence word that can only follow a particular predecessor.
Understanding and interpreting written material is a separate area
Subject area 4 gives you short reading selections and asks questions about them. Everything required is in the selection, and no special knowledge is needed or rewarded — the wrong choices are typically the ones that add a fact the passage does not carry, or overstate one it does.
