Based on published standards

- Web Content Accessibility Guidelines (WCAG) 2.2W3C28 questions
- The Service StandardGOV.UK2 questions

Try a sample question
Your sign-up form uses placeholder text instead of labels, and the placeholder disappears as people type. Which problem does this cause?
- It slows the page down
- It breaks dark mode
- It only affects mobile users
- People with memory or cognitive impairments, and screen reader users, lose the field's label
Show the answer
D. People with memory or cognitive impairments, and screen reader users, lose the field's label — Placeholders aren't labels: they vanish on input and often have poor contrast. Visible labels keep the field's meaning available to everyone. The real test has 20 questions like this.
