If you have ever stared at your IB predicted scores and felt your stomach drop (or float), you are not alone. In most schools, those IB predictions are built from a surprisingly human mix of evidence, rubrics, and professional judgment. They can open university doors early, shape confidence, and sometimes trigger panic. But once you understand how schools predict IB scores, the process becomes less mysterious and more manageable.
This guide walks you through the real inputs behind IB predictions and what you can do (this week) to influence the evidence teachers actually use.
The fast checklist: what most schools use to predict IB scores
When teachers predict IB scores, they rarely rely on a single test. Most departments blend:
-
Mock exams and timed paper practice (often the biggest factor)
-
Internal Assessment (IA) progress and rubric performance (commonly 20--30% of the final subject mark)
-
In-class assessments: topic tests, quizzes, essays, labs
-
Consistency and trend: are you improving, stable, or drifting?
-
Teacher judgment + moderation: departments align standards across classes
-
Core signals: TOK and EE drafts can affect the total diploma points forecast
If you want a student-friendly way to translate your current marks into an estimate, try the IB Grade Calculator as a quick reality check. It is not what your school submits, but it helps you think in the same direction as your teachers.
What predicted IB scores actually are (and what they are not)
A predicted IB score is a teacher-generated forecast of your likely final performance, based on the best evidence available before the exams. Universities use predicted grades to make offers early or to set conditions. Schools also use them internally to flag who needs intervention.
But predicted IB scores are not a promise. They are a snapshot of your current proof. And proof is something you can create.

How schools predict IB scores (what teachers are really looking at)
Mock exams: the closest thing to future you
Schools love mocks because mocks behave like the real IB exam: time pressure, mixed topics, command terms, and mark allocations that punish vagueness.
Teachers typically compare your mock performance to recent grade boundaries and to past cohorts at your school. If your mock answers show the right structure (even with gaps), your predicted IB score often rises because structure is repeatable.
You can build that structure deliberately using RevisionDojo’s Questionbank for exam-style drilling, then stepping up to full rehearsals with IB Predicted Papers.
Internal Assessments: the “slow marks” that still move predictions
IAs usually account for around 20--30% of the final IB grade in many subjects, so strong IA work is not just coursework pride, it is statistical weight.
Teachers use the official criteria language: analysis vs description, method clarity, evaluation quality, appropriate evidence, and communication. Even before final submission, your IA trajectory can influence your predicted IB score because it signals how you handle criteria-based marking.
If your school allows feedback on drafts, treat each comment like an exam markscheme clue. Then use RevisionDojo’s Grading tools to stress-test your drafts, and the Coursework Library to see what high-scoring work tends to look like under the rubric.
Classwork and assessments: the “quiet data” that adds up
In many schools, predicted IB scores include the boring stuff: weekly quizzes, unit tests, homework accuracy, essay plans, lab write-ups, oral practice.
This is not about being the loudest student in the room. It is about being reliably present in the evidence. A teacher who has six clean data points for you can justify a stronger prediction than a teacher who only has one brilliant performance and three missing submissions.
A practical routine is to pair Study Notes for clarity with daily Flashcards for recall, then prove it with questions. RevisionDojo’s workflow is built for that: Study Notes, Flashcards, AI Chat, and targeted practice from the Questionbank.

Trend analysis: schools predict momentum, not mood
Teachers often look less at your best day and more at your direction of travel. Are your timed marks improving? Are your essays getting more precise? Are your mistakes changing from “I do not know the topic” to “I lost marks on evaluation”? That shift is predictive.
When you hear “we look at trends,” it usually means your last 6--10 weeks matter disproportionately.
Teacher judgment and moderation: why two students with the same mark can get different predictions
Predicted IB scores are not only math. Departments often hold moderation meetings to align standards across teachers and classes. That reduces bias, but it also means teachers need defensible reasoning.
If you are borderline between two grades, “I will work harder” is not evidence. A marked timed response, an improved IA section aligned to criteria, or a consistent run of Questionbank results is evidence.
How to influence your predicted IB score (without begging)
Build an “evidence update” your teacher can use
If you want a predicted IB score to change, bring proof that matches the input sources:
-
One timed paper section (or mock-style set)
-
Marked corrections with brief notes: what you changed and why
-
A short list of recurring error types (content, method, command term, time)
-
One improved coursework segment aligned to criteria
RevisionDojo makes this easier because you can do a timed set in the Questionbank, use AI Chat to understand the markscheme logic, then repeat with Mock Exams or Predicted Papers.

Use a calm, specific message to teachers
A good predicted-grade conversation is precise and respectful:
-
What evidence did you use for my predicted IB grade?
-
Which upcoming assessment could change it?
-
What would a “grade higher” response look like in this subject?
This turns the conversation into an academic plan, not a negotiation.
Conclusion: treat predicted IB scores as a proof problem
A predicted IB score is not a verdict about your potential. It is your school’s best estimate based on the evidence in front of them: mocks, IA progress, classroom performance, and a trend line that tries to guess where you will land.
If you want that number to move, the path is simple (not easy): create better evidence. Use RevisionDojo to run the loop that teachers trust most in the IB: learn fast with Study Notes, retain with Flashcards, apply with the Questionbank, get unstuck with AI Chat, rehearse with Predicted Papers and Mock Exams, and sharpen work with Grading tools, the Coursework Library, and Tutors.
Start today with one timed set, one correction log, and one message asking what “grade higher” looks like. In the IB, that is how predictions change: quietly, repeatedly, on paper.
