Errata
A question bank that claims to be perfect is hiding something. This page is the permanent, public ledger of every confirmed error in a StudyCove question: what was wrong, how we fixed it, and credit to whoever caught it. When an error is confirmed we retire the question immediately and publish the entry here within 24 hours — and because your practice history pins the exact version of every question you saw, you can always tell whether an erratum affected you.
None so far.
Not because nobody’s looking — every question runs the verification pipeline on our how-we-check page before it ships. The first confirmed error will appear here, permanently, with credit to whoever finds it. If you think you’ve found one, report it from the question itself.
