Authored difficulty versus observed performance
Methodology and limitations
Computed from aggregate Lucky the Banker practice-answer records joined to the checked-in Series 79 question bank. Answer records and distinct users are reported separately. Rankings require at least 10 answer records and 5 distinct users per question, or 30 answer records and the same user minimum per topic or section. Rows without a user ID, rows not matching the current question bank, and configured internal or QA accounts are excluded. No names, emails, user IDs, session histories, or per-user results are published. Small samples are withheld, not extrapolated.
This is LTB practice-platform data, not a representative sample of every candidate and not an official pass-rate study. A miss rate describes this dataset only; it does not predict an individual candidate’s exam outcome.
