How we decide what to publish

1. 01

   Provenance is part of the interface, not a footnote

   We link to controlling statutes, regulations and official guidance. Source notes identify the rule or calculation being taught. A general chapter link is context, not proof of every sentence; time-sensitive claims need a specific section and an actual check date.

2. 02

   Unverified means unpublished, not softened

   An unsupported claim must be investigated or removed. Qualifications such as 'generally' belong where a rule has exceptions, not where its author lacks evidence. Monthly all-attempt pass rates cannot be relabeled first-time rates; separately published first-time figures need their own cohort and period.

3. 03

   When DRE contradicts itself, we show both positions

   The calculator question is the live example. DRE's Examination Control Information lists calculators among prohibited items, while Regulation 2763(a)(6) quoted on the same page expressly permits a simple non-programmable one. We quote both, attribute both, and resolve neither, because DRE has not. The fact is flagged in the data so a later edit cannot quietly smooth it over.

4. 04

   Derived numbers are labeled as derived

   DRE publishes approximate percentage weights, not a fixed question count for each area. The illustrative area counts alongside the blueprint multiply each weight by 150 and round independently; they sum to 152, not 150. Our practice-set allocator instead distributes exactly the requested number of items. Neither calculation establishes the composition of a particular DRE exam form.

5. 05

   One source of truth, and the site audits itself against it

   Shared registries hold content areas, weights, topic lists, fees, examination mechanics, forms and the tool inventory. Question and tool counts are derived from their data. Tests check the weights, calculation examples, topic representation and content synchronization. A release manifest binds the delivered files, question fields and PDF downloads to the reviewed candidate; changing a hash requires review, not automatic approval.

6. 06

   Calculation methods need independently checked examples

   The test suite exercises calculation methods with known inputs and expected outputs, including tax thresholds, fractional rates, proration dates and negative seller proceeds. These examples do not test every possible input. Learners should still check the problem's units, assumptions and rounding direction. Regression cases preserve fixes when the interface or formulas change.

7. 07

   No real examination questions, ever

   Business and Professions Code section 123 prohibits unauthorized reproduction and use of licensing-exam questions. Violations can carry misdemeanor penalties and liability for actual damages up to $10,000 plus costs; section 10153.01 permits a candidate bar of up to three years. Our original practice items teach the published topics, not recalled DRE questions.

8. 08

   No pass guarantee, and no competitor claim without evidence

   We do not publish a pass prediction without validated outcome evidence. Comparisons with other resources need documented support. The practice-evidence check offers study advice, not a calibrated probability or a guarantee.

9. 09

   Complete results before any signup

   Public practice provides explanations without an email wall. Learn mode reveals feedback after an answer; test mode waits until the result screen. Calculators show their assumptions and calculation method. The website and paid app have different boundaries, which the pricing page explains.

On October 11, 2026, we reviewed all seven content-area guides, 249 public practice questions, 86 articles, 18 formula lessons, seven additional math lessons, 125 glossary entries, seven study plans and the downloadable study material against official sources available through October 10. We corrected legal distinctions, answer explanations and calculator behavior, then checked the PDFs against the revised website text. This is an editorial source review, not DRE approval or a promise that no error remains.

Earlier source-check dates remain part of the record. The public mock exams still offer 25 or 50 questions. The separate mobile and paid-app question banks were outside this website audit.

This resource uses AI-assisted drafting, editorial review and software tests. We compare legal claims with controlling sources, check the assumptions and arithmetic in worked examples, and record material corrections. Automated checks help detect changed content and calculation defects; they do not establish a pass rate or imply DRE endorsement.
