You can feel it weeks before the exams: the quiet mental math running in the background.
If I get a 6 here and a 5 there… do I still clear my university offer? Do I still get the IB diploma? And what if the grade boundaries move?
That anxiety is normal. But it’s also optional.
When you turn vague worry into a concrete estimate, your brain stops spinning and starts planning. That’s the point of the RevisionDojo IB Grade Calculator: it helps IB students in 2025 translate practice marks into an estimated 0--45 total, using the right session and timezone.

The quick checklist to predict your IB score (without guesswork)
Before you touch any calculator, collect evidence. Not vibes.
-
Your most realistic timed marks for each IB subject (mocks, timed sections, or full practice sets)
-
Your best estimate for coursework-level performance (IA progress and rubric confidence)
-
The correct session + timezone you’ll be examined in
-
The right set of IB Grade Boundaries for that session
-
Your TOK and EE expectations (because core points matter)
Once you have those, predicting your IB score becomes less like fortune-telling and more like budgeting.
Why a 2025 IB score prediction changes how you revise
A prediction is not a promise. But it is a mirror.
When you see an estimated IB total, three useful things happen:
First, you stop treating every subject like an emergency. You can spot which subject is quietly dragging your total down.
Second, you get specific. “I need to improve Paper 2” becomes “I need +8 raw marks to hit the next boundary.” That’s actionable.
Third, you protect your energy. IB prep punishes the students who sprint in every direction. It rewards the students who move the needle where it counts.

How the RevisionDojo Grade Calculator works for IB 2025
The RevisionDojo IB Grade Calculator is designed around how the IB actually reports outcomes: subject grades (1--7), plus core points (0--3), producing a total out of 45.
Step one: choose the right session and timezone
In IB, session details matter. Some boundaries vary by timezone, and you don’t want to predict using someone else’s scale. Pick your exam session (for example, May 2025) and your timezone first.
Step two: enter marks for all six IB subjects
You’ll add your subject marks based on your most representative practice. The quality of your output depends on the honesty of your inputs.
A useful rule: if you only ever did untimed questions, don’t treat those marks as your exam reality. Take a timed block first.
To create those timed blocks, RevisionDojo’s ecosystem helps you generate evidence quickly:
-
Use the Questionbank to drill topics and then mix them the way IB papers do.
-
Use Mock Exams and Predicted Papers to pressure-test timing and stamina.
-
If you get stuck mid-question, use RevisionDojo AI Chat to clarify the step you keep missing, then immediately retry the question.
Step three: add TOK and EE for core points
Many IB students ignore core points until it’s late. But those points can be the difference between “safe” and “stress.” Your prediction should include TOK and the Extended Essay expectations so the final estimate reflects your full diploma reality.

IB grade boundaries: what to do with them (and what not to do)
Grade boundaries are a translation layer. They turn raw marks into the 1--7 grade universities see.
They’re also where students tend to spiral.
Here’s the healthier approach for IB 2025:
-
Use boundaries to understand distance: how many marks separate you from the next grade?
-
Use boundaries to prioritize effort: which component gives you the fastest return?
-
Don’t obsess over “predicting the boundary.” Your job is to bank marks you control.
For a calm, detailed explanation of how boundaries are set, read: IB Grade Boundaries: How They're Actually Calculated.
Turn an IB prediction into an action plan (the RevisionDojo way)
An IB score prediction is most useful when it immediately tells you what to do next.
Here’s a simple loop that works well in the final stretch:
Learn faster than you rewrite
Use RevisionDojo as your home base, and pull clarity from Study Notes instead of rewriting chapters. Notes are where confusion dies quickly.
Recall daily, even when you’re tired
Add short sessions with Flashcards. In IB, consistency beats hero days. Your memory is like a subscription: stop paying, it cancels.
Practice with feedback that actually teaches
Run targeted sets in the Questionbank, then use the built-in Grading tools and feedback loops to see why marks were lost.
Rehearse under pressure
Do timed practice weekly using predicted sets and mocks. If you want a strategy for doing this without burning out, use: How to Study for IB Exams Without Burning Out.

Predict your IB score, then earn it
A calculator won’t sit the exams for you. But it can stop you from studying blindly.
If you’re preparing for IB exams in 2025, start here: open the RevisionDojo IB Grade Calculator, choose your session and timezone, and enter your most honest marks. Then use IB Grade Boundaries to understand your distance to the next grade.
After that, RevisionDojo becomes the system that turns “I hope” into “I can prove it” -- with Study Notes, Flashcards, AI Chat, Questionbank, Grading tools, Predicted Papers, Mock Exams, a Coursework Library, and Tutors when you want human-level diagnosis.
Your predicted IB score isn’t a verdict. It’s a map. Use it.
