The Mathematics IGCSE Paper 1H — Higher tier past papers in the collection that assess quadratic equations.

These papers were matched to quadratic equations automatically, by keyword patterns in their questions and mark schemes. A hand-check of 100 randomly chosen matches, each read against the source question paper and the specification's own statements for the topic, found 99 that genuinely assess the topic and 1 that does not — 99% (95% confidence interval 94.6–99.8%). That is a good way to find practice on a topic, not proof a paper covers it, and a paper missing from this list may still assess it. The topics are the specification’s headings, which are broad: one question on any statement under a heading was enough.
