How many IB points do I need to pass?

For the IB Diploma, the headline number is typically 24 points. But the score alone isn’t the whole story, because the IB also checks minimum performance across HL and SL, completion of CAS, and limits on very low grades. This is why two students can both say “I got 24” and have completely different outcomes. If one student has an E in TOK or EE, the diploma can be at risk even with enough subject points. If another student has too many low subject grades, the diploma can also be withheld. The practical move is to track both your running total and your risk areas weekly so nothing surprises you.

What is the maximum IB score and where does it come from?

The maximum IB score is 45 points. You get up to 42 points from your six subjects because each is graded from 1 to 7. Then you add up to 3 core points based on your combined TOK and EE results. Students sometimes assume the core is “small,” but those 1–3 points can change university outcomes significantly. The core can also be a hidden threat if TOK or EE goes badly, because an E grade can impact whether the diploma is awarded. If you’re aiming for a top score, treat TOK and EE like score multipliers, not side quests.

Are HL and SL scored differently in the IB?

HL and SL courses in the IB are both graded on the same 1–7 scale, so the point value is identical. The difference is the demand: HL usually has more content, more assessment time, or more complex question styles. That means HL often requires more deliberate exam technique training, not just more revision hours. Many students lose HL marks from avoidable issues like timing, command terms, or incomplete method marks. If your HL points are lagging, don’t just reread notes; do targeted timed sets and get them graded. That’s where tools like RevisionDojo’s Questionbank, AI grading, and Mock Exams can translate effort into higher HL scores.

How Do IB Points Work? Simple Guide to IB Scoring

You can feel it the first time someone says, “What’s your predicted?” in the hallway.

It’s not just a question. In the IB, points become a kind of language: numbers that represent relief, pressure, possibility, and sometimes panic. But the scoring system is actually simpler than it looks, once you see the pieces and how they add up.

This guide breaks down how IB points work in a way you can use right now while you’re revising for exams.

IB points at a glance (quick checklist)

If you want the whole IB scoring system in one screen, here it is:

The IB Diploma is scored out of 45 points.
You take six subjects, each scored 1 to 7 (maximum 42 points total).
You can earn up to 3 bonus points from TOK + EE.
CAS is required to receive the diploma, but it doesn’t add points.
To pass the IB Diploma, you generally need 24 points plus meeting key conditions.

If you want to estimate where you stand quickly, use the IB Grade Calculator to map practice marks to likely point totals.

What is the IB point system (and why 45 matters)

The IB Diploma Programme combines breadth (six subjects across groups) with depth (Higher Level courses) and a core that tests how you think.

Your final IB points are essentially:

6 subject grades (each 1–7)
plus TOK/EE core points (0–3)

That’s why 45 matters: it’s the clearest summary of your overall performance across everything the IB values. Universities often set offers in IB points, so understanding the scoring rules helps you plan revision with less guesswork and more control.

For a broader overview of the programme structure, you can also explore the International Baccalaureate (IB) hub.

How the 45 IB points are actually calculated

The 42 subject points (six subjects x 7)

In the IB, you take six subjects, one from each group (with some flexibility). Each subject receives a final grade from 1 to 7, where 7 is the highest.

So the maximum from subjects is:

6 subjects x 7 = 42 points

You’ll study a mix of SL and HL, and the IB requires at least three HL subjects (and at most four). HL and SL are both graded on the same 1–7 scale, but HL typically has more content depth and assessment demands.

The 3 core points (TOK + EE)

On top of the 42 subject points, the IB awards up to 3 additional points based on your combined results in:

Theory of Knowledge (TOK)
Extended Essay (EE)

TOK and EE are graded using letters (A to E). Your combination of TOK and EE grades translates into 0–3 core points.

One critical detail: an E in TOK or EE can mean the diploma is not awarded, even if your subject points look strong. It’s one of those IB rules that feels harsh until you realize what it’s protecting: minimum competence across the full programme.

The IB Diploma pass requirements (simple but important)

Students often hear “you need 24 points” and stop there. But the IB has several conditions designed to prevent a diploma that’s technically “24” but academically uneven.

While requirements can include multiple checks, the common expectations students should remember are:

At least 24 total IB points (including core points)
Meeting minimum point totals across HL and SL subjects (often referenced as 12 HL points and 9 SL points)
Completing CAS requirements
Avoiding prohibited combinations of low subject grades (for example, a 1 in any subject is a serious problem)

If you’re revising and want to keep this practical, think in two layers:

Points layer: are you on track for your target total?
Rules layer: are you accidentally triggering a “diploma not awarded” condition?

A calm way to manage both layers is to run routine check-ins using the RevisionDojo App for IB exam prep, then adjust your weekly plan based on what’s actually slipping.

How IB subjects are graded (internal vs external)

Your final subject grade in the IB usually comes from a combination of:

Internal assessment (IA): coursework like labs, investigations, oral components, portfolios, performances, or written tasks (teacher-marked, then moderated)
External assessment: final exams (and sometimes externally assessed coursework)

This is why the smartest IB revision doesn’t ignore coursework even when exams get close. You’re not only studying content; you’re training accuracy against markschemes and criteria.

To build that exam accuracy efficiently, RevisionDojo’s Questionbank lets you practice exam-style questions by topic and see where marks are actually earned.

Predicted vs final IB scores (what they mean for you)

Predicted scores can feel like a verdict, but they’re really a snapshot based on limited evidence: coursework quality, class tests, and mock performance.

Final IB scores are different. They reflect how you actually perform in the assessed components, including the final exams.

Here’s the mindset that helps:

Predicted scores tell you what your current habits produce.
Final scores tell you what your trained habits can produce under pressure.

If you want a structured way to turn predicted anxiety into measurable improvement, build your revision around timed practice and feedback loops. Two useful starting points are:

A simple IB points strategy (so your score goes up, not just your stress)

The easiest way to raise IB points is to stop treating them like motivation and start treating them like navigation.

Try this weekly loop:

Learn: Use targeted explanations from RevisionDojo’s Study Notes (pair this with Digital IB Study Notes).
Recall: Use IB Flashcards with spaced repetition and refine technique with Flashcard techniques for long-term retention in IB.
Apply: Drill weak topics with the IB Question Bank guide.
Rehearse: Sit full papers using IB Predicted Papers and then review mistakes like a scientist.

This is also where RevisionDojo’s AI Chat, Grading tools, Mock Exams, Coursework Library, and Tutors matter: you’re not just doing more work; you’re shortening the feedback cycle that turns effort into points.

Closing: IB points are a system you can learn

The IB scoring system looks intimidating because it compresses two years of work into one number. But once you understand the structure (42 from subjects, up to 3 from TOK/EE, plus key diploma rules), it stops being mysterious. And when something stops being mysterious, it becomes manageable.

If you want to turn IB points into a plan, start with the IB Grade Calculator, then build a weekly routine using RevisionDojo’s Study Notes, Flashcards, Questionbank, AI Chat, Grading tools, Predicted Papers, Mock Exams, Coursework Library, and Tutors. Your target score isn’t a wish. In the IB, it’s a project.
