RevisionDojo currently lists 44 IB Diploma Programme subject and core hubs, covering Groups 1-5 and Theory of Knowledge. This includes widely taught SL and HL subjects, selected Language A and Language B courses, SL-only options, and separate hubs for syllabuses undergoing transition.
The platform combines Study Notes, Flashcards, Questionbank practice, Jojo AI, grading tools, and Predicted Papers. However, listing a subject does not mean that every feature has the same depth, so students should inspect their exact hub before relying on it.
How to check RevisionDojo subject coverage
The live RevisionDojo IB subject directory provides the most current coverage information. When checking a hub, confirm three details:
- The exact course title, including Language and Literature versus Literature.
- Your SL or HL level.
- Your examination year, especially when a syllabus is changing.
Predicted Papers are unofficial practice examinations, not predictions of exact IB questions. Grading support may include essay marking, oral feedback, or IA, EE, and TOK feedback, depending on the subject.
Every IB subject area covered
The table consolidates the 44 directory entries. Separate entries for old and revised syllabuses are counted individually.
| IB area | Subject hubs currently listed | Levels |
|---|---|---|
| Core | Theory of Knowledge | Core component |
| Group 1 | Arabic A; Arabic A Literature; Chinese A Language and Literature; English A Language and Literature; English A Literature; French A; French A Literature; German A; German A Literature; Spanish A; Spanish A Literature | SL and HL |
| Group 2 | Arabic ab initio; Arabic B; Chinese B; English B; French ab initio; French B; German ab initio; German B; Spanish ab initio; Spanish B | Ab initio is SL only; Language B is SL and HL |
| Group 3 | Business Management; Digital Society; Economics; Geography; Global Politics; History through 2027; History from 2028; Philosophy; earlier Psychology; Psychology from 2027; World Religions | Usually SL and HL; World Religions is SL only |
| Groups 3 and 4 | Environmental Systems and Societies, revised syllabus | SL and HL |
| Group 4 | Biology; Chemistry; earlier Computer Science; Computer Science from 2027; earlier Design Technology; Design Technology from 2027; Physics; Sports, Exercise and Health Science | SL and HL |
| Group 5 | Mathematics: Analysis and Approaches; Mathematics: Applications and Interpretation | SL and HL |
Most major hubs provide some combination of questions, notes, Flashcards, grading, and examination practice. Particularly broad coverage appears in subjects such as English A, Business Management, Economics, Biology, Chemistry, Mathematics, Psychology, Global Politics, Computer Science, and Design Technology. Inventory can still differ by topic and syllabus version.
Subjects without dedicated hubs
The main directory does not currently list complete Group 6 hubs for Visual Arts, Film, Music, Theatre, or Dance among the 44 entries. RevisionDojo may provide broader arts or coursework guidance, but this is not equivalent to a dedicated subject hub containing a full Questionbank, notes, Flashcards, and papers.
The Extended Essay and Creativity, Activity, Service are also excluded from the subject count. EE assistance is available through coursework support, while CAS is a core requirement without a 1-7 subject grade.
Syllabus changes and examination years
Students must use resources aligned with their examination session. RevisionDojo has separate hubs for Psychology, Computer Science, and Design Technology with first assessment in 2027, plus a revised History hub for first assessment in 2028.
Do not assume earlier questions match a revised syllabus merely because the subject name is unchanged. Compare your school's course outline with the hub topics and assessment structure. RevisionDojo has not published a complete release schedule for every missing subject or future feature, so unannounced resources should be treated as unavailable.
Why features differ between subjects
Subjects require different forms of practice. Mathematics and sciences benefit from calculation, graph, and data-response questions, whereas Language A courses depend more heavily on textual analysis, oral preparation, and extended writing feedback.
Language B and ab initio students also need vocabulary retrieval, listening, speaking, and exposure to authentic media. Online resources can structure practice, but they cannot fully replace conversation, teacher correction, or sustained reading in the target language.
Jojo AI works alongside RevisionDojo's subject materials. A student can review a note, attempt a question, request an explanation of one error, and then retest the same skill. This is more effective than asking for complete answers without making an independent attempt.
RevisionDojo compared with alternatives
Save My Exams provides concise notes, topic questions, Flashcards, mock examinations, and marking tools across supported IB courses. Kognity functions primarily as an interactive digital textbook and school teaching platform, with assignments and teacher analytics.
RevisionDojo is suited to students wanting an IB-specific, self-directed system combining subject hubs, Jojo AI, custom practice, exam simulation, and coursework feedback. The best platform still depends on the depth available for your exact subject rather than the total number of subjects advertised.
A practical RevisionDojo study sequence
- Use Study Notes to clarify one weak concept.
- Test recall with Flashcards.
- Complete a focused Questionbank set without notes.
- Ask Jojo AI to explain a specific misconception.
- Use an appropriate grader for essays, orals, IA, EE, or TOK work.
- Attempt Predicted Papers or Mock Exams after topic practice.
Conclusion
RevisionDojo covers 44 DP subject and core hubs, with most major courses available at both SL and HL. Its main advantage is the connection between learning materials, practice, feedback, and retesting. Check your course title, level, syllabus, and examination year, then use RevisionDojo's Study Notes, Questionbank, Flashcards, Jojo AI, and Mock Exams according to the resources available.
