Estimate your IB Diploma score across six subjects and core points. Plan realistic target outcomes with a clear score projection out of 45.
IB grade boundaries vary by subject and exam session. Use this tool for planning and target-setting rather than official score reporting.
The IB Diploma combines subject achievement with core performance to produce one overall score used in admissions decisions globally.
Each IB subject is graded from 1 to 7. The six subjects combine for up to 42 points before adding core points.
Theory of Knowledge and Extended Essay together contribute up to 3 additional points through the IB core matrix.
Grade boundaries can vary by exam session and subject, so estimates should guide planning but not replace official results.
Subject Points = S1 + S2 + S3 + S4 + S5 + S6 (Max 42)
Each subject contributes from 1 to 7 points based on official IB assessment criteria and boundaries.
Overall IB = Subject Points + Core Points (TOK + EE), Max 45
Core adds up to 3 points and often makes a meaningful difference near key admissions thresholds.
| IB Total | General Band | Admissions Signal | Suggested Focus |
|---|---|---|---|
| 24-27 | Passing edge | Basic diploma range | Target weakest subjects first. |
| 28-33 | Solid | Broad admissions competitiveness | Improve one HL and core points. |
| 34-39 | Strong | Selective university range | Refine high-weight assessments. |
| 40-45 | Top-tier | Highly competitive profile | Maintain consistency across all subjects. |
Your IB total is calculated by adding six subject grades (each from 1 to 7, for a maximum of 42) plus up to 3 core points from TOK and Extended Essay, for a maximum of 45.
A common benchmark is 24 points, but passing the diploma also depends on specific conditions such as minimum subject performance and core requirements.
Core points come from Theory of Knowledge (TOK) and the Extended Essay (EE). Together they contribute between 0 and 3 extra points to your diploma total.
This tool is designed for planning. Official IB grade boundaries vary by subject and exam session, so final published grades can differ from estimated values.
Yes. Predicted grades are school estimates before final assessments and moderation. Final results can move up or down depending on exam performance and official boundaries.
Most universities evaluate both. The total score is important, but subject-level strength, HL/SL choices, and consistency across courses also influence admissions.
Many competitive universities view 34+ as strong, while highly selective programs often expect upper-30s to 40+ depending on program and country.
Use it to model scenarios, set score targets, and decide where to focus study effort by identifying subjects with the highest potential gain.
Core points can help, but they are capped at 3. Most score movement still comes from improving subject grades across your six courses.
Yes, this estimator is built around the IB Diploma scoring framework that combines six subjects and TOK/EE core points.
