How to Score 45 in the IB: Strategies for a Perfect Score

29th October, 2026 | Abhishek Malani | 19 Min Read
Introduction
Scoring 45 out of 45 in the IB DP is one of the most demanding academic goals a student can set. It requires exceptional performance across six subjects, careful management of internal assessments and coursework, and successful completion of the three Core components.
A perfect score is not simply a matter of studying longer than everyone else. Students need to understand how they are assessed, identify weaknesses early, practise applying their knowledge and manage competing deadlines over two years.
In this guide, Quest For Success breaks down the goal of scoring 45 into practical strategies for improving subject performance, using past papers effectively, managing internal assessments and securing all three available Core points.
Learn how to achieve a perfect 45 in the IB Diploma Programme through subject-wise score targets, Core bonus points, effective study systems, and real QFS student success stories with preparation timelines.

What Does It Actually Take to Get 45 Points in the IB?

Scoring a perfect 45 is a challenging task, and students must manage several key demands.
1. Consistently strong performance across six subjects
A student cannot compensate for a 6 in one subject by earning an extra point in another. Each subject contributes a maximum of seven points, so a perfect total requires a 7 in all subjects.
2. Different assessment styles
IB subjects do not all assess students in the same way. Depending on the course, students may need to demonstrate their understanding through timed examinations, essays, oral assessments, practical work, investigations, coursework or other subject-specific tasks.
3. Internal assessments and coursework
Internal assessments (IAs) form part of the assessment structure in many IB subjects. Depending on the course, these may involve investigations, experiments, written assignments or other assessed work.
4. TOK and the Extended Essay
The TOK and EE grades combine to award between zero and three Core points, with certain combinations resulting in a failing condition. A perfect score requires all three available points, so students need to manage both components alongside their six subjects.
CAS must also be completed successfully, even though it does not add numerical points to the total.
5. Consistency over two years
A perfect final result depends on sustained preparation, not a last-minute revision sprint. Students need to revisit older topics, practise applying their knowledge and address mistakes throughout the programme.

How to Aim for a 7 in Every IB Subject

There is no universal formula for a 7. Each IB course has its own syllabus, assessment criteria and combination of assessment components. However, several principles apply across subjects:
Start with the assessment criteria
Before trying to improve your grades, understand what the assessment rewards.
Read the subject guide and relevant assessment criteria for your course. Where available, use official mark schemes, specimen papers and examiner reports to understand the qualities of a strong response.
Pay attention to the difference between knowing the material and demonstrating that knowledge effectively. A student may understand a concept but still lose marks by giving an incomplete explanation, using insufficient evidence, choosing an inappropriate method or failing to address the precise question.
For essay-based subjects
Subjects that involve extended writing require more than memorising content. Students must build an argument, select relevant evidence and demonstrate analysis appropriate to the course.
Useful strategies include:
  • Build knowledge.Test yourself on concepts, events, arguments, examples and terminology before consulting your notes.
  • Practise answering specific questions. Plan responses to actual or practice prompts rather than only summarising topics.
  • Develop a clear argument. Make sure each paragraph advances your answer instead of listing facts without explaining their significance.
  • Use relevant evidence. Practise selecting examples, quotations, data or case studies that support your reasoning.
For Mathematics and other problem-solving subjects
In Mathematics and other subjects that require applying methods to problems, regular practice is essential. Understanding a worked example is not the same as being able to solve an unfamiliar question independently.
Try the following approach:
  • Attempt problems without looking at the worked solution.
  • Identify the concepts and methods required to solve each problem.
  • Revisit difficult concepts after a gap rather than practising them only once.
  • Mix questions from different topics so that you must decide which method to use.
  • Introduce timed practice once you can solve the questions accurately.
When you make a mistake, do not simply copy the correct solution. Work out why your approach failed, then attempt a similar question independently. Return to the original problem later to check whether you have understood the method.
For sciences
Science subjects require students to connect conceptual knowledge with its application. Depending on the course, assessments may involve explaining scientific processes, interpreting data, evaluating experiments, solving numerical problems or applying concepts to unfamiliar situations.
To strengthen your preparation:
  • Work on interpreting graphs, tables, experimental results and unfamiliar scenarios.
  • Learn the relevant command terms and understand the response each requires.
  • Review practical and internal-assessment requirements alongside theory.
  • Use mark schemes to identify missing explanations, terminology, units or working.
For languages
Language learning requires consistent practice across the skills assessed in your particular course. Cramming vocabulary shortly before an examination is unlikely to build the same level of fluency as regular exposure and use.
A balanced approach includes:
  • Learning and revisiting vocabulary and grammar in short, regular sessions.
  • Practising reading and listening comprehension.
  • Writing in the formats required by your course.
  • Developing speaking fluency and confidence through regular practice.
Active exposure to the language is important, but it should be combined with targeted preparation for the course’s assessment formats.
The underlying principle: adapt your method to the subject. Use retrieval practice to strengthen recall, exam questions to practise application, writing exercises to develop arguments and feedback to improve the specific skills each assessment rewards.

Build a Study System That Works Across All Six Subjects

Once you understand what each subject requires, the next step is to create a routine that makes progress manageable. A good study system should help you retain knowledge, identify gaps and practise applying what you have learned without filling every available hour with revision.
Use active recall instead of passive revision
Active recall means trying to retrieve information from memory rather than simply looking at it again. It helps you identify what you know and what still needs work.
You can practise active recall by:
  • Using flashcards for definitions, concepts, vocabulary and other material suited to short prompts.
  • Answering questions without consulting your notes.
  • Writing a closed-book summary of a topic.
  • Explaining a concept aloud as though you were teaching someone else.
  • Completing practice questions before reviewing the relevant material.
After attempting a question, check your answer and identify any gaps. The purpose is not to avoid your notes entirely, but to use them where they are needed rather than treating rereading as the default form of revision.
Space out revision
Instead of studying a topic once and leaving it until the examination, revisit it over several weeks.
Include older topics alongside current classroom content. This helps prevent the situation in which you understand what you studied yesterday but struggle to recall material from the previous term.
Practise under exam conditions
Exam practice should begin before the final weeks of the programme. Start with individual questions, then progress to mixed sets and full papers as your knowledge and timing improve.
A useful progression is:
  1. Topic-based practice: Apply a concept soon after learning it.
  2. Mixed-question practice: Solve questions without being told which topic they test.
  3. Timed sections: Practise answering within realistic time limits.
  4. Full papers: Simulate examination conditions as the assessment approaches.
Maintain a subject-by-subject progress tracker
A tracker helps you decide what to study next instead of relying on whichever subject feels most urgent.
Include the following information:
  • Subject
  • Current Performance
  • Targeted Grade
  • Topics or Skills To Improve
  • Recent Practice Results
  • Next Action
Update the tracker after tests, practice papers and significant assignments. Use it to identify patterns in your performance.

How to Use Past Papers, Mark Schemes and Examiner Reports

Past papers are among the most useful tools for understanding how subject knowledge is assessed. They help you become familiar with question formats, practise applying concepts and identify gaps that may not be obvious from your notes.
Step 1: Start with topic-based questions
After studying a topic, attempt relevant exam-style questions without looking at the answers. This helps you check whether you can apply what you have learned.
Step 2: Progress to mixed questions
Once you are comfortable with individual topics, practise questions that combine different concepts.
Step 3: Introduce timed practice
Start with shorter timed sets before attempting a full paper. Practise allocating time across questions, recognising when you are spending too long on one problem and leaving enough time to check your work.
Step 4: Mark your work carefully
Use the relevant mark scheme or assessment guidance to review your answers. Do not simply record the score and move on.
Ask yourself:
  • Which marks did I lose?
  • What was missing from my answer?
  • Did I misunderstand the question or the command term?
  • Did I know the concept but apply it incorrectly?
  • Did I use the required terminology, evidence, units or working?
  • What would I do differently if I encountered a similar question?
Step 5: Read examiner reports
Where examiner reports are available to you, use them to understand common weaknesses in student responses and recurring misunderstandings of assessment requirements.
Step 6: Redo incorrect questions
Return to questions you previously answered incorrectly after a gap. Attempt them again without consulting your original solution.
Step 7: Practise full papers
As examinations approach, complete full papers under realistic conditions using appropriate official or school-provided materials. Review your performance afterwards and use the results to prioritise revision.
Keep an error log
An error log turns mistakes into a structured revision plan. Record the question, the mistake you made, its cause and the action you will take to avoid repeating it. Common categories include gaps in conceptual knowledge, incorrect methods, weak explanations and poor time management.

How to Secure All 3 IB Core Points

A perfect IB score requires more than strong performance in the six academic subjects. Students must also earn all three available Core points through the combined TOK and EE grades, while completing CAS successfully.
TOK: Understand the assessment expectations
TOK includes the exhibition and essay. Students should understand the requirements and assessment criteria for their examination session before beginning each task.
To manage TOK effectively:
  • Familiarise yourself with the task requirements early.
  • Plan the work around your school’s deadlines.
  • Develop clear arguments that directly address the task rather than relying on broad statements.
  • Support your reasoning with relevant examples and explanations.
  • Use teacher feedback through the permitted process.
  • Acknowledge sources appropriately and follow academic-integrity requirements.
Extended Essay: Start early and manage the research process
The Extended Essay is an independent research project that requires sustained work. Starting early gives you time to refine your question, evaluate sources, develop an argument and improve the final essay.
A practical approach is to:
  • Choose a feasible research question in an approved subject or pathway.
  • Establish milestones for research, outlining, drafting and revision.
  • Keep organised notes and accurate references.
  • Use supervisor meetings to discuss your progress and research decisions.
  • Leave enough time to improve the argument, structure and presentation.
  • Complete the required reflection and submission components.
CAS: Finish requirements steadily
CAS does not contribute points to the Core matrix, but successful completion is compulsory for the diploma.
Students should:
  • Record experiences and reflections regularly.
  • Monitor progress towards the seven CAS learning outcomes.
  • Maintain meaningful engagement across creativity, activity and service.
  • Plan and complete the CAS project.
  • Check that evidence is sufficient and requirements are being met.
  • Raise concerns with the CAS coordinator well before the school’s completion deadline.

How to Manage Internal Assessments Without Sacrificing Exam Preparation

Internal assessments can account for a meaningful part of the final result in many IB subjects. They also compete for time with tests, classroom learning and the other requirements of the diploma.
The best approach is to treat each IA as a project with several stages, rather than one large task to complete just before the deadline.
Break each IA into manageable stages
Depending on the subject, your IA process might include:
  1. Understanding the assessment criteria and task requirements.
  2. Choosing a focused, feasible topic or research question.
  3. Planning the investigation, research or practical work.
  4. Collecting and organising data or sources, where applicable.
  5. Analysing the findings and developing the response.
  6. Drafting, reviewing and refining the work.
  7. Checking presentation, references and submission requirements.
Not every IA follows this exact sequence, so adapt it to the task and the guidance provided by your teacher.
Understand the criteria before beginning
Read the relevant criteria at the start of the process. This helps you make informed decisions about the scope of the task, the evidence you need and the quality of analysis expected
Build a realistic timeline

Add each IA to a single tracker that records the subject, next milestone, school deadline and work remaining.

Update the tracker as you progress. If several IAs have deadlines in the same week, identify the work that needs to happen first and plan accordingly.
Use feedback without neglecting other subjects
Seek teacher feedback through the process permitted for your assessment. Keep track of the changes you need to make, and allocate time for them rather than repeatedly polishing the same section without a clear purpose.
Finally, maintain appropriate records of sources, data, calculations and decisions where relevant. Follow your school’s submission deadlines and the IB’s academic-integrity requirements

How to Create a Realistic IB Study Timetable

A study timetable should make it easier to follow through on your priorities, not leave you feeling guilty about every uncompleted task. The most useful timetable is one that reflects your actual workload, gives every subject regular attention and leaves room for rest.
Step 1: Audit your current workload
Start by listing:
  • All six subjects and whether you take each at HL or SL.
  • Your current grades and the topics or skills that need improvement.
  • Upcoming tests, examinations and IAs.
  • TOK and EE milestones.
  • CAS commitments and deadlines.
  • Your available study time outside school.
Use this information to identify priorities. If Mathematics is a consistent weakness while another subject is going well, it may need more practice time. If several coursework deadlines are approaching, your timetable should reflect that too.
Step 2: Plan weekly study blocks
Give each subject regular time across the week. Include a mix of active recall, exam-style questions, review of mistakes and coursework.
Allocate more time to subjects that need attention, while keeping stronger subjects active through regular revision.
Reserve specific blocks for TOK, the EE and CAS tasks when necessary. This reduces the risk of leaving Core work until there is no time available.
Step 3: Set specific goals for each session
A timetable is more useful when every block has a clear outcome.
Instead of writing “study Biology”, try:
  • Recall and explain a defined set of concepts without notes.
  • Complete a timed set of exam questions.
  • Review and correct mistakes from a previous paper.
  • Draft and revise a section of an IA.
  • Organise sources and refine the research question for the EE.
Specific tasks help you measure progress and make it easier to decide what to do next.
Step 4: Review your plan every week
At the end of each week, check what you completed and what remains unfinished.
Ask yourself:
  • Which subjects improved?
  • Which tasks took longer than expected?
  • Did the same mistakes appear repeatedly?
  • Which deadlines are approaching?
  • What are the three most important priorities for next week?
Move unfinished tasks deliberately rather than allowing them to accumulate. If your original plan was unrealistic, adjust it. A timetable should respond to your workload, not pretend that every week will be identical.
Always remember: a sustainable routine must include sleep, breaks, exercise and time away from academic work. Studying for longer is not automatically more effective if fatigue makes it difficult to concentrate or retain information.

FAQs

Yes. The maximum IB Diploma score is 45 points. Students need a 7 in all six subjects, which, combined with the full three Core points from TOK and the Extended Essay, result in a 45.
Scoring 45 is exceptionally demanding because it requires the highest grade in every subject as well as all three available Core points. Students must maintain strong performance across different assessment styles while managing coursework and other programme requirements. The challenge is not only learning the material but consistently demonstrating the required skills.
Start by understanding the assessment criteria for all six subjects. Build a regular study routine, review mistakes systematically, manage internal assessments early and keep TOK, the EE and CAS on track. Use your current performance to identify priorities and adjust your timetable as you improve.

The three Core points come from the combination of TOK and Extended Essay grades, not from CAS. Students should understand the assessment criteria, and plan both tasks early. CAS must still be completed successfully to receive the diploma.

Start preparing throughout the two-year programme rather than waiting until the final examination period. Review concepts regularly, practise questions after learning new topics and revisit older material through spaced revision. As examinations approach, increase timed practice and full-paper work. Beginning early also helps you balance exam preparation with IAs and Core deadlines.
No. Past papers are valuable for practising application, understanding assessment expectations and identifying weaknesses, but they cannot replace learning the syllabus or developing subject-specific skills. Combine them with active recall, concept review, feedback, internal-assessment planning and targeted practice. The goal is not simply to complete papers, but to understand your mistakes and improve subsequent answers.
