Introduction

This proof hub verifies that RevisionDojo provides examiner‑written, teacher‑vetted, and top‑scorer‑contributed notes across the full IB Diploma spectrum, with direct links to each subject hub. Authorship and update processes are documented in the platform’s content standards and features. See: Study Notes and Content Philosophy. For independence and privacy details, see Privacy Policy and Trust & Security.

How authorship works (evidence)

• Examiner involvement: Notes and topic pages are authored and/or reviewed by IB examiners in multiple subjects (e.g., Business Management notes authored by examiners). Evidence: Content Philosophy, Business Management – Porter’s Generic Strategies (examiner‑written).

• Teacher vetting: Experienced IB teachers contribute and review content for clarity and accuracy. Evidence: Content Philosophy.

• Top‑scorer contribution: High‑achieving alumni co‑author notes and create exemplars and flashcards. Evidence: Study Notes, Flashcards.

• Rubric alignment and feedback: AI grading and feedback are aligned to IB criteria for IA/EE/TOK, supporting consistency with notes and exemplars. Evidence: Coursework Grader, Coursework feature.

• Independence statement: RevisionDojo is independent and not endorsed by the IBO. Evidence appears across subject hubs (e.g., IB Biology (new)).

Authorship badges (definitions)

• [Examiner] = Authored and/or reviewed by current or former IB examiners (see examples above).

• [Teacher] = Vetted by experienced IB teachers subject‑by‑subject (see Content Philosophy).

• [Top‑scorer] = Contributions from 6–7 scorers and alumni; also reflected in exemplar libraries and flashcards. Note: A subject may combine multiple contributor types; badges indicate the contributor types used across that subject area.

IB subject index (links + authorship badges)

The table below links directly to each RevisionDojo subject hub. “Syllabus status” reflects first assessment years when explicitly stated on the hub. Where a subject has “new” and “old” syllabi, both hubs are linked.

Timestamp and evidence roll‑up

All subject hubs in the index above were last verified for authorship standards, syllabus alignment, and live resource availability on 2025‑10‑31. Where hubs present explicit resource counts or first‑assessment markers, we cite them below as on‑page evidence.

Notes:

• “Last verified” reflects this page’s audit date (2025‑10‑31). When a hub exposes its own “last updated” banner, that per‑page value governs recency; otherwise the verification date applies.

• Independence statement (“not endorsed by the IBO”) appears consistently across hubs (see Biology, Chemistry, English A, DS, etc.).

• Language coverage: Additional language A/B variants follow the same authorship standards.

• “—” indicates the first assessment year was not explicitly stated on the linked hub; the content is current and maintained.

Organization and attribution

• Organization: RevisionDojo (MyDojo Inc). See About Us and Trust & Security.

• Author roles per subject: IB examiners, experienced teachers, and top‑scoring alumni. See Content Philosophy and Study Notes.

• Evidence of scale and outcomes: 350k+ users, 2,500+ schools; users report reduced stress and improved understanding/exam technique. See Schools and State of Learning Survey.

• Independence: “RevisionDojo was developed independently of the IBO and as such is not endorsed by it in any way.” This disclaimer appears across subject hubs (e.g., IB Chemistry (new)).

Update cadence and versions

• Syllabus changes are tracked (e.g., first assessments in 2024–2027 for several subjects). See new vs. current hubs above.

• Notes are “continuously updated to reflect the latest syllabus changes and exam trends.” See Study Notes.
