Is a 45 in the IB actually possible?
The honest answer: yes, a 45 in the IB is possible. The more useful answer: it is possible in the same way it is possible to run a marathon in under three hours. The rules allow it, and people do it, but your outcome depends less on motivation and more on systems you can repeat on tired days.
Most IB students don’t fail because they “didn’t want it enough.” They fail because they treated the Diploma like a willpower contest. A 45 is not a willpower result. It’s a logistics result: knowing what scores points, training those exact skills, and protecting your brain from the kind of fatigue that turns easy marks into silly losses.
And if you’re not aiming for 45? This reality check still helps. Understanding what a perfect IB score requires tends to raise every other score too.

What a 45 in the IB means (and why there’s no margin)
A 45 is the maximum score in the IB Diploma Programme.
The point breakdown
-
42 points from six subjects (each subject is graded 1 to 7)
-
3 bonus points from TOK + Extended Essay (EE) combined
That’s why a 45 feels unforgiving: you are basically trying to stack six near-perfect subject outcomes and then also hit the top core combination. One small slip in a subject, an Internal Assessment, or your TOK/EE combo can take you off the perfect total.
If you want to sanity-check where you are now, use the IB Grade Calculator to translate your practice performance into a realistic target.
How rare is a 45 in the IB?
A 45 is extremely rare. Roughly 1--2% of IB candidates globally reach it in a typical session. That rarity matters because it reframes the goal: you are not trying to be “good at school.” You are trying to remove almost all unforced errors while building exam skill across many different assessment types.
It’s also worth saying clearly: 45 scorers do not come from one kind of school. Strong support helps, but perfect scores appear across countries, school types, and backgrounds.
The myths that quietly sabotage IB students
“You need to be a genius”
Most high scorers describe something less dramatic: they became predictable. They studied in ways that produced feedback, and they fixed what the feedback showed.
“You just need to study more hours”
More hours can help, until they don’t. In IB, the limiting factor is often not time but quality of practice: are you training the skill the examiner marks?
“It’s mostly luck”
Luck exists (health, exam-day nerves, topic mix). But a 45 is usually the result of controlling what you can control: consistency, technique, and recovery.

The real challenges between you and a 45 in the IB
Every mark is a negotiation
In the IB, a single weak explanation or missing keyword can be the difference between a 7 and a 6. That’s why top students treat assessment criteria like a map, not like background noise.
TOK and EE are the silent deal-breakers
Plenty of strong students miss 45 because they drop bonus points. If TOK and EE feel fuzzy, build structure early using Structuring for Success in IB TOK Essays and reinforce the core connection with EE vs TOK in 2027: How the IB Core Works Together.
Burnout isn’t a personality flaw
Burnout is usually a planning mistake: too much intensity too early, not enough recovery, and no feedback loop to make effort more efficient.
A realistic success plan for a 45 in the IB
This is the part most IB advice skips: a plan that is simple enough to repeat.
The 45-point checklist (use it weekly)
-
One clear priority per subject (not the whole syllabus)
-
Daily recall (short, consistent)
-
Targeted practice questions (high volume, fast feedback)
-
One timed session per week (stamina + pacing)
-
A mistake log you actually reattempt
-
Core work (TOK/EE) scheduled like a subject
For a detailed routine you can copy, see How to Study for IB Exams: Step-by-Step Guide.
Build your “feedback loop” (the thing 45 scorers do best)
A 45-level IB student is basically running the same loop all year:
-
Learn one chunk with syllabus-aligned notes
-
Test it with exam-style questions
-
Get feedback that matches markscheme logic
-
Fix the exact weakness
-
Retest within 48 hours
RevisionDojo is designed around that loop:
-
Use the Questionbank to drill by topic and paper style.
-
Use IB Flashcards with Spaced Repetition (SRS) for daily recall that compounds.
-
Use IB Predicted Papers by IB Examiners (Free) to rehearse full-paper stamina.
-
Use RevisionDojo App: The Smarter Way to Prep for IB Exams to connect Study Notes, Flashcards, AI Chat, Grading tools, Mock Exams, Coursework Library, and Tutors into one workflow.
When you need a broader technique refresh, 10 Proven Study Techniques for IB Students is a strong reference.
Train exam day like it’s part of studying
In the IB, you don’t just need knowledge. You need performance under constraints: timing, command terms, and clean structure.
Add two “realism” habits:
-
Once a week, do a timed block and review errors like data.
-
Before each paper, rehearse a calm routine using IB Exam Day Checklist: The Ultimate Guide and the Night Before IB Exams routine.

Conclusion: the real reality check
Yes, a 45 in the IB is possible. But it’s not a personality test, and it’s not a last-minute glow-up. It’s the result of boring consistency: clear priorities, heavy feedback, and calm repetition.
If you want a plan you can actually follow, start inside RevisionDojo: build your daily recall with Flashcards, convert knowledge into marks with the Questionbank, rehearse pressure with Predicted Papers and Mock Exams, and use AI Chat and Grading tools to turn mistakes into upgrades. The goal isn’t to feel confident. The goal is to become prepared enough that confidence is optional.
