One day, an IB student I know stared at a prediction spreadsheet like it was a weather forecast. The numbers were fine, technically. But the feeling wasn’t. Because in the IB, a “fine” number can still feel like a trap: 5s that don’t add up the way you expected, a core grade that changes the total, a university offer that suddenly sounds very specific.
That’s why understanding IB points matters. Not as trivia, but as strategy. When you know how the points are built, you stop guessing. You can plan your time, protect your energy, and revise with intent.
The IB points system in one quick checklist
If you only remember one thing, make it this:
-
You take 6 IB subjects, each scored 1 to 7.
-
That’s a maximum of 42 subject points.
-
You can earn up to 3 bonus points from TOK + EE.
-
Your maximum IB Diploma score is 45 points.
-
CAS is required but not scored.
When you want to sanity-check your current total, use the IB Grade Calculator to see how subject marks and core points combine.
What the 1 to 7 scale actually means in IB
Every IB subject ends with a grade from 1 to 7. It’s simple on paper, but the meaning is very different from a percentage system.
A 7 doesn’t mean “near perfect.” It means “top-band performance against IB criteria,” which includes how you structure answers, use command terms, and show the depth expected for your level.
Here’s the intuitive way to think about it:
-
7: consistently excellent and exam-ready
-
6: very strong, with only minor gaps
-
5: solid understanding, but technique or depth may slip
-
4: acceptable, but fragile under pressure
-
3 and below: high risk without intervention
Grade boundaries (the raw marks needed for each grade) shift each session. So the same mark can land differently depending on exam difficulty and global performance. If you want a deeper breakdown of how the scale works across assessments, read What Is the Grading Scale for IB Exams?.
How the 45 IB points are built
The IB score is a two-part total:
Subject points: 42 maximum
You take six subjects (usually 3 HL + 3 SL). Each subject is worth up to 7 points.
So the ceiling is:
- 6 subjects × 7 = 42 points
HL subjects don’t give more points than SL subjects. They’re just harder to score highly in because the assessment demands are higher.
If you’re still choosing subjects or helping a younger student understand what “IB” even includes, the International Baccalaureate (IB) overview is a clean place to start.
Core points: 3 maximum (TOK + EE)
Then come the extra points students forget about until the last minute: Theory of Knowledge (TOK) and the Extended Essay (EE).
TOK and EE are graded separately, and then combined using a matrix to award 0 to 3 bonus points.
CAS is different: it must be completed, but it doesn’t add points.
If your TOK or EE feels vague, make it practical. Use a guide that talks in criteria, not inspiration. Start with the IB Extended Essay Guide, and if you’re trying to make TOK ideas strengthen your EE (and sometimes raise core outcomes), see How to Use TOK to Enhance Your Extended Essay.
What you need to pass the IB Diploma (and what usually causes surprise)
The headline requirement is simple: 24 points.
But the real IB diploma award rules include conditions that can catch people off guard when one subject drops or the core goes wrong.
Common requirements include:
-
At least 24 total points
-
Complete CAS
-
Meet minimum expectations across SL and HL totals
-
Avoid failing conditions triggered by very low subject grades and/or core outcomes
The most important idea for students preparing for exams: don’t treat 24 as a target. Treat 24 as the absolute floor with traps underneath it. Build margin.

How universities interpret IB points
Universities don’t just look at the total IB points. They also care about patterns:
-
Are your HL subjects strong in the area you’re applying for?
-
Do you meet subject-specific requirements (like Math or a science)?
-
Do your grades show consistency, or a weak link?
In many systems (especially the UK), offers are written directly in points. In others (like the US), IB points support a broader application and may translate into course credit in some cases.
This is why “one more point” can matter. Not because it changes who you are, but because it can change which door opens.
How to improve your IB points efficiently (the loop that works)
A quiet truth about the IB is that effort isn’t the same as improvement. Improvement comes from a loop:
-
Practice a skill the way you’ll be assessed
-
Get feedback that matches markscheme logic
-
Fix one specific pattern
-
Repeat before you forget
RevisionDojo is built around that loop. Students typically mix:
-
Study Notes to learn or patch concepts (Study Notes)
-
Flashcards to keep facts and definitions active (Flashcards)
-
Questionbank for targeted IB-style practice with feedback (Questionbank)
-
AI Chat to clarify what you keep avoiding (inside RevisionDojo)
-
Grading tools for coursework-style feedback (IB Coursework Grader)
-
Predicted Papers to rehearse full-paper timing and topic coverage (IB Predicted Papers)
-
Mock Exams for stamina and pressure training (available within RevisionDojo workflows)
-
Coursework Library and Tutors when you need exemplars and human guidance (IB Coursework Examples: IA, EE and TOK Exemplars)

Conclusion: treat IB points like a map, not a mystery
The IB points system isn’t complicated to punish you. It’s complicated because it’s trying to measure different kinds of learning at once: subject mastery, research, reflection, and sustained effort.
Once you understand how IB points work, your revision becomes calmer. You stop bargaining with the unknown and start building points deliberately: protect your six subject grades, take TOK and EE seriously, and run timed practice early enough to learn from it.
If you want one place to do that--with Questionbank practice, Study Notes, Flashcards, AI Chat, Grading tools, Predicted Papers, Mock Exams, a Coursework Library, and Tutors when you need them--start with RevisionDojo for IB.
