Corrections policy
What we correct
CBI Prep corrects confirmed factual errors, broken or misleading preparation guidance, technical mistakes that affect a learner’s understanding, and outdated claims when authoritative information has changed.
How corrections are handled
Reports are checked against the relevant page, test item or source. Material errors are corrected in the content or product rather than hidden. Minor style edits may be made without a public correction note.
Report an issue
When reporting a preparation-content problem, include the page or test name, module, question number when applicable, and a concise explanation of the suspected issue. Do not include passwords or payment-card information.
