128 questions. That is the inventory at a11y.quest, a drill-based resource targeting web accessibility competency across five specific domains: WCAG 2.2 compliance, ARIA implementation, semantic HTML, keyboard navigation, and contrast ratios.
The value is not in the question count. It is in the plain-English answer format, which strips out spec jargon and forces the underlying concept into plain terms. That approach exposes whether you actually understand accessibility or just recognize its vocabulary.
Worth reading for the WCAG 2.2 and ARIA sections specifically, where the gap between developer assumption and actual standard is widest. Bookmark it as a recurring audit of your own knowledge, not a one-time skim.
