NinetynineVenn diagram: counts of items belonging to overlapping categories (3-4 sets)
CAT has tested this idea 33 times across 7 papers, from 2017 to 2024. Solve one, and the others are the same method with different numbers or wording, which is why repeated concepts are the most efficient thing to practise.
