IB Predicted Grades Calculator (Out of 45)
Enter your six IB subject predicted grades (1 to 7), plus your TOK and Extended Essay grades to estimate your total predicted score.
This is an estimation tool for planning and reflection. Final IB results are determined by official IB assessments and grade boundaries.
How this IB predicted grades calculator works
The calculator uses the standard IB Diploma scoring model: six subjects worth up to 7 points each, plus up to 3 core points from Theory of Knowledge (TOK) and the Extended Essay (EE). That gives a maximum possible score of 45 points.
- Subjects: 6 courses × maximum 7 points each = 42 points.
- Core: TOK + EE combined = 0 to 3 points.
- Total predicted score: Subject total + core points.
IB core points (TOK + EE) matrix used
The calculator uses the commonly used TOK/EE points matrix approach. Rows are EE grades and columns are TOK grades.
| EE \ TOK | A | B | C | D | E |
|---|---|---|---|---|---|
| A | 3 | 3 | 2 | 2 | Fail |
| B | 3 | 2 | 2 | 1 | Fail |
| C | 2 | 2 | 1 | 0 | Fail |
| D | 2 | 1 | 0 | 0 | Fail |
| E | Fail | Fail | Fail | Fail | Fail |
If either TOK or EE is E, or if a grade is missing (N), this tool flags it as a failing/missing core condition in the estimate.
Why predicted grades matter
Predicted grades play an important role in university applications, scholarship opportunities, and setting realistic academic goals. A clear predicted score can help you decide where to focus your effort before final exams and internal assessments are submitted.
What schools and universities look for
- Consistency across Higher Level and Standard Level subjects
- Strong HL performance for competitive courses
- Evidence of progress over time (not just one strong test)
- Healthy core performance (TOK/EE) that avoids risk conditions
How to improve your predicted IB score
1) Target one grade jump at a time
Moving from a 5 to a 6 in one HL subject can have a big impact on your total. Focus on the subjects where you are closest to the next boundary and where improvement is realistic.
2) Master markscheme language
In the IB, wording matters. Whether you are writing an essay, solving a data-based question, or building an argument in TOK, align your answers with rubric criteria and command terms.
3) Use feedback loops
After each mock, quiz, or IA draft, create a quick review log:
- What cost me marks?
- Was the issue knowledge, structure, or timing?
- What exact action will I take before the next assessment?
4) Protect your consistency
Predicted grades are often based on long-term evidence. Last-minute cramming can help in the short run, but steady performance across terms usually has the strongest impact on teacher predictions.
Frequently asked questions
Is this an official IB calculator?
No. It is an independent planning tool. Your school and the IB Organization determine official predicted and final grades.
Can this tool guarantee diploma success?
No calculator can guarantee outcomes. This tool gives a simplified estimate and highlights major core-risk conditions. Full diploma award rules include additional details your coordinator can confirm.
What is a strong predicted score?
This depends on your goals, subject mix, and target universities. As a broad guide, many competitive programs look for totals in the mid-to-high 30s and above, with stronger expectations for selective courses.
Final thoughts
An IB predicted grades calculator is most useful when combined with a clear study plan. Use your estimate as a starting point, identify your highest-return improvements, and build momentum week by week. Even small improvements across several subjects can add up quickly on a 45-point scale.
