Scoring 45/45 in the IB requires a grade 7 in all six Higher Level and Standard Level subjects, plus all three core points from Theory of Knowledge and the Extended Essay. Under the official core points matrix, three points require an A in TOK and an A in the EE. Creativity, activity, service does not add points, but CAS must still be completed.
Achieving this result demands top-band performance across examinations, essays, investigations, oral work, coursework and independent research. This article explains how to score 45/45 in the IB through practical preparation, accurate performance tracking and coordinated planning.
What an IB perfect score requires
The calculation is 6 × 7 + 3 = 45.
| Diploma component | Requirement for 45/45 | Maximum contribution |
|---|---|---|
| Six academic subjects | Grade 7 in every subject | 42 points |
| Theory of Knowledge | Grade A | Combined with EE |
| Extended Essay | Grade A | Combined with TOK |
| TOK and EE matrix | A plus A | 3 points |
| CAS | Satisfactory completion | 0 points |
Both HL and SL subjects contribute a maximum of seven points. HL courses contain greater depth and normally receive more teaching time, but an HL result is not multiplied in the diploma total. A student cannot compensate for a 6 at SL by performing especially well in an HL subject.
The IB uses criterion-related assessment, so work is judged against defined standards rather than ranked against classmates. Component marks are weighted and aggregated before session-specific grade boundaries convert the result into a grade from 1-7. The IB assessment overview explains how examinations, internally assessed work and externally assessed coursework contribute.
A 45 does not require full marks on every paper or IA. It requires an overall weighted result above the grade 7 boundary in every subject, plus A grades in TOK and the EE. Since boundaries can change between sessions, historical boundaries are planning references rather than guaranteed thresholds.
How rare is a 45 in the IB?
The IB no longer publishes the exact number of candidates receiving 45 points. Its May 2025 final statistical bulletin reports that 9.8% of candidates scored within the 40-45 band. That category includes six different totals, so it cannot establish the proportion receiving exactly 45.
Claims about a precise current 45-point rate may rely on outdated data or unsupported estimates. The defensible conclusion is that 45 is substantially rarer than the broader 40-45 category and should be treated as an exceptional outcome.
Build a grade 7 margin in every subject
Do not target the lowest historical boundary that once produced a 7. That leaves little protection against unfamiliar questions, marking variation, illness, timing problems or boundary changes. Instead, aim to produce repeated grade 7 results under timed conditions, with a reasonable margin above recent boundaries.
Create a component map for every subject:
| Information to record | Why it matters |
|---|---|
| Current syllabus and components | Prevents preparation for outdated assessments |
| Component weightings | Identifies where marks have the greatest effect |
| Recent timed scores | Provides evidence of current performance |
| IA or oral estimate | Shows how much pressure remains on examinations |
| Recurring error types | Converts weaknesses into specific tasks |
| Recent grade boundaries | Adds context without predicting future thresholds |
A grade calculator based on practice marks can organize this information, but the inputs should come from independent, timed work. Untimed questions completed with notes are not reliable forecasts.
Match revision to the subject
The same method will not work equally well across six subjects.
- Language and literature: Practise unseen analysis, thesis construction, comparisons and complete timed responses.
- Language acquisition: Combine vocabulary retrieval with listening, reading, speaking and timed writing. Oral fluency requires consistent practice.
- Individuals and societies: Learn precise concepts and evidence, then apply them through command terms such as evaluate, discuss and compare.
- Sciences: Alternate conceptual explanation with calculations, data analysis, experimental reasoning and unfamiliar applications.
- Mathematics: Solve problems without worked examples beside you. Correct errors, reproduce the method from memory and apply it to a different problem.
- The arts and electives: Schedule portfolio, performance and process work according to the current subject criteria.
There is no objectively easiest subject combination for an IB perfect score. Suitable choices depend on strengths, prior preparation, interests and university requirements. A supposedly easy subject can become difficult when it conflicts with those factors.
Protect coursework marks early
Coursework contributes to the final subject result. Strong internal assessment can provide useful protection, while weak coursework increases dependence on exceptional final papers. Forms and weightings vary, so follow the current guide supplied by your school.
Use a structured process:
- Translate each criterion into visible evidence. Determine what an assessor must find in the submitted work.
- Choose a feasible task. A focused investigation completed thoroughly is safer than an ambitious project with weak evidence.
- Set intermediate deadlines. Separate approval, research, data collection, analysis, drafting and final checks.
- Use permitted feedback early. Seek guidance while the method and reasoning can still be changed.
- Audit the submission. Check citations, labels, units, appendices, word limits and declarations.
The RevisionDojo Coursework Grader can identify areas to discuss with a teacher, but it does not provide an official IB mark. Teacher guidance and current subject documentation remain authoritative.
Academic integrity is non-negotiable. AI-generated material is not automatically the student’s own work, and included AI output must be acknowledged appropriately. Use Jojo AI for concept clarification, practice or questioning an argument, not to produce assessed writing submitted as original work. Follow the IB guidance on artificial intelligence and your school’s rules.
Secure all three core points
The official core points matrix awards three points only for A plus A. An A in one core component and a B in the other produces two points, reducing the maximum total to 44 even with six subject 7s.
Theory of Knowledge
TOK rewards analysis of knowledge questions, not decorative philosophical language. Strong work makes a precise claim, supports it with a specific example, examines assumptions or limitations, and explains how the discussion answers the prescribed title or exhibition prompt.
For the essay, test interpretations before drafting and define important terms in context. For the exhibition, objects must support focused analysis of the selected prompt rather than act as illustrations added afterwards. Always use the titles, prompts and guidance for your assessment session.
Extended Essay
The IB Extended Essay overview describes independent, self-directed research culminating in a paper of up to 4,000 words. A strong EE begins with a focused, researchable question and an appropriate subject-specific method. It needs sustained analysis that answers the question, not merely a report of collected information.
Keep a source and methods log, meet the supervisor with specific questions, and revise the overall argument before polishing sentences. Elegant writing cannot compensate for an unmanageable research question or unsuitable evidence.
CAS
CAS contributes no points, but completion is required for the diploma. Record experiences and reflections steadily, respond to coordinator requirements and monitor the required learning outcomes. Leaving documentation until the end creates avoidable administrative risk.
Use a practice, feedback and retest cycle
A 45-level routine is defined by reliable evidence, not extreme study hours. Passive rereading can feel fluent, but examinations require independent retrieval, application and decision-making.
Use this cycle:
- Refresh one tightly defined topic.
- Attempt relevant questions without notes.
- Mark the response against the markscheme or criteria.
- Classify each lost mark by cause.
- Repair the precise weakness.
- Retest it on a new question after a delay.
Useful categories include knowledge gap, method error, misread command term, weak evidence, poor structure, careless execution and timing. “Revise Biology” is vague. “Distinguish competitive and non-competitive inhibition in unfamiliar graphs” creates a trainable task.
The RevisionDojo IB resources hub supports this process through Study Notes, Flashcards, the Questionbank and Jojo AI. Each resource should serve a clear purpose, such as clarification, retrieval, application, feedback or retesting.
Train timed performance and manage the diploma
Knowing the syllabus is not the same as producing top-band work under examination conditions. Timing, question selection, stamina and checking routines need deliberate practice. Begin with timed sections and progress to full papers after covering enough content.
A balanced week should include short retrieval sessions, targeted question sets, one coursework or core checkpoint, one timed assessment and detailed review. Protect genuine rest and sleep because reduced attention and accuracy can cancel out additional late-night study.
Use one calendar for examinations, school tests, oral assessments, IAs, TOK, the EE and CAS. Review it weekly and select two or three priorities based on evidence while maintaining every subject. RevisionDojo’s guidance on how 45-point students prepare and online mock exam practice can help structure simulations. Predicted papers are realistic practice, not forecasts of exact questions.
Common mistakes that prevent a 45
- Targeting the boundary: A narrow historical grade 7 is not a secure prediction.
- Treating every subject identically: Essays, speaking and mathematical problems require different practice.
- Perfecting notes instead of producing answers: Notes should support retrieval, not replace it.
- Postponing TOK and the EE: Losing one core point makes 45 impossible.
- Trusting one strong mock: Readiness must appear across several papers.
- Ignoring recurring errors: Units, definitions, timing and weak evidence links accumulate.
- Using unauthorized assistance: Academic misconduct can threaten the assessment result.
- Sacrificing health: Exhaustion reduces consistent precision.
Conclusion
Learning how to score 45/45 in the IB begins with the exact requirement: six subject 7s, an A in TOK, an A in the EE and completed CAS. Reaching that standard requires strong coursework, timed performance, criterion-aware writing, precise error tracking and coordinated diploma management.
No platform or schedule can guarantee an IB perfect score. The objective is to build consistent evidence that every component meets the required standard. RevisionDojo can support this through its Questionbank, Flashcards, Study Notes, Mock Exams, Coursework Grader, Grade Calculator and Jojo AI when each tool forms part of a practice, feedback and retest cycle.
