If you are asking how predicted grades get set and what to do if you disagree, the short answer is that your school sets them using academic evidence and teacher judgment. The IB does not calculate university application predictions, and there is no IB-wide appeal system. Any review must follow your school’s procedure before its submission deadline.
This matters particularly from September-November, when many IB students complete university applications. A prompt, evidence-based request is more likely to receive careful consideration than a last-minute demand for an additional point.
What an IB predicted grade means
The IB defines a predicted grade as the teacher’s prediction of the grade a candidate is expected to achieve, based on evidence of the candidate’s work and the teacher’s knowledge of IB standards. Diploma Programme subjects use the 1-7 scale. TOK and the Extended Essay use the A-E scale when schools report predictions to the IB.
Students may encounter two related estimates:
- Forecasts supplied to universities during the application cycle
- Predicted grades submitted later to the IB for examination administration
Schools and application systems do not always use the terminology consistently. A university forecast set in autumn may be decided at a different time from the prediction eventually submitted to the IB.
A predicted grade is not an official result, guaranteed minimum, or reward for effort. It is a professional forecast of your likely achievement based on the evidence currently available. Universities may consider it alongside transcripts, references, admissions tests, written applications, portfolios, or interviews.
How predicted grades get set
There is no universal IB formula requiring every school to weight evidence in the same way. The official principle is that predictions should reflect the student’s work and IB standards, while the detailed method is usually determined by the school or subject department.
Teachers commonly consider:
- Mock examinations and timed assessments
- Topic tests, essays, laboratory work, and oral tasks
- Internal Assessment progress and criterion-based performance
- Results across DP1 and the opening part of DP2
- Consistency, recent improvement, and performance under examination conditions
- Departmental moderation and previous experience with IB standards
One excellent test does not automatically establish a higher prediction. Equally, one weak result should not necessarily outweigh a sustained pattern of stronger work. Teachers normally consider which grade best represents the complete evidence and whether the student has demonstrated that standard reliably.
A simplified example
Suppose a History student wants a predicted 6. Their recent timed essays are 5, 5, 6, and 6, while their Internal Assessment draft is around the 6 level. A teacher might reasonably predict either a 5 or 6 depending on school policy, recent evidence, and whether the student can sustain a 6 across the examination components.
Saying “I need a 6 for university” explains why the decision matters, but it does not prove that a 6 is academically justified. A persuasive discussion must focus on assessed performance.
Why autumn timing matters
The prediction used for an application must be ready before the school submits that application. Schools often impose internal deadlines earlier than official platform deadlines so counsellors can verify qualifications, references, and supporting documents.
For 2027 UCAS entry, completed applications could be submitted from 1 September 2026. The equal consideration deadline is 15 October 2026 at 18:00 UK time for Oxford, Cambridge, and most medicine, dentistry, and veterinary medicine or science courses. For most other undergraduate courses, it is 13 January 2027 at 18:00 UK time.
Do not assume the January UCAS deadline gives you until January to improve a prediction. Your school may finalize forecasts in October or November.
| Application route | How predictions are generally handled | What to check |
|---|---|---|
| UCAS | The registered centre enters predictions for pending qualifications | School deadline, review policy, and submission status |
| Common App | The counsellor supplies school reports and academic records | College requirements and later reporting arrangements |
| Direct application | The school may provide a signed prediction or transcript | Required format and document deadline |
| National service | Rules vary by country and institution | Whether predicted IB results are accepted |

What to do if you disagree
1. Check the school policy
Ask your teacher, counsellor, or DP coordinator how predictions are determined, when they become final, and whether a formal review is available. Some schools accept written requests, while others use meetings or departmental reviews. This is a school procedure, not an IB appeal.
2. Ask how the grade was reached
Begin with specific questions:
- Which assessments were considered?
- How much weight was given to recent timed work?
- Was IA progress included?
- Was the prediction moderated?
- What separates the current grade from the next grade?
Understanding the reason helps you respond effectively. Weak evaluation requires a different plan from incomplete syllabus knowledge or poor time management.
3. Prepare a concise evidence file
Bring relevant results, dates, and teacher feedback. Persuasive evidence might include two recent timed assessments at the requested level, a consistent improvement pattern, or rubric-based coursework performance.
Unmarked practice, heavily assisted homework, and online estimates are weaker evidence. The RevisionDojo IB Grade Calculator can help interpret representative marks, but it cannot issue an official prediction.
4. Request a realistic remedy
You might ask for:
- Reconsideration of overlooked evidence
- Review by a second teacher or department head
- One defined assessment opportunity before the deadline
- Correction of a factual or data-entry error
- Written confirmation of the final decision
A fair review checks whether the judgment was reasonable. It does not require unlimited reassessment until the preferred grade is achieved.
5. Escalate appropriately
If the teacher cannot resolve the concern, follow the stated route through the head of department, DP coordinator, counsellor, or senior administrator. Keep communication factual and respectful. Raise documented extenuating circumstances through the appropriate school process.
Building stronger evidence
The strongest evidence is recent, supervised, syllabus-relevant, and comparable with final assessment conditions. If the school permits new evidence, identify the component holding your grade down, practise targeted questions, study each lost mark, and complete a similar task under timed conditions.
RevisionDojo’s Questionbank and early-application guide can support targeted practice, while timed mock exams can test whether improvement survives realistic conditions. Jojo AI can help identify errors, but the school decides which evidence it recognizes.
Avoid these common mistakes:
- Arguing only from university requirements
- Comparing yourself with classmates
- Relying on one unusually strong mark
- Waiting until submission day
- Treating a grade calculator as decisive
- Pressuring or threatening staff
A disappointing prediction is not automatically unfair. The key question is whether the available evidence makes a higher result the most defensible forecast.
If the application has already been submitted
For UCAS, predicted grades cannot be changed inside the application after submission. UCAS advises students seeking an amendment to discuss it with their chosen universities. An institution may consider corrected information, but reconsideration is not guaranteed.
Common App works differently. Counsellors may submit midyear information, while an Optional Report can communicate suitable updates or corrections. Requirements vary, so official information should normally come from the school rather than the student.
If no amendment is possible, review your university list. Compare your predicted total, HL grades, and required subjects with entry requirements, then include ambitious, realistic, and safer choices. RevisionDojo’s guide to how predicted grades affect university offers explains how overall points, HL scores, and prerequisites influence decisions.
Conclusion
Predicted grades are school-set professional forecasts based on academic evidence and knowledge of IB standards. If you disagree, act before the internal deadline, ask how the judgment was reached, present recent comparable evidence, and follow the school’s review route.
RevisionDojo cannot change a prediction, but its Grade Calculator, Questionbank, Mock Exams, and Jojo AI can help identify weaknesses and produce stronger evidence before the review window closes.
