How to Interpret Your Grade from the Tool
- The embedded grader calculates your total score out of 20 marks across all five criteria.
- Here's how to interpret your results:
- 18-20 marks (Grade 7 territory): Excellent work with sophisticated mathematical applications. Minor refinements needed.
- 15-17 marks (Grade 6 range): Strong investigation with good mathematical modeling. Focus on application depth and interpretation.
- 12-14 marks (Grade 5 level): Competent work meeting basic requirements. Strengthen mathematical applications and real-world connections.
- 9-11 marks (Grade 4 range): Adequate foundation but needs significant improvement. Review mathematical content and practical applications.
- Below 9 marks (Grade 3 or lower): Major revision required across most criteria. Restructure approach and strengthen mathematical fundamentals.
If you're between bands, focus on Criterion D (Use of Mathematics) - it offers the biggest impact for improvement.
Grade Boundaries & Converting Your Mark
IB Math AI IA grade boundaries are consistent but can vary slightly by session:
| IB Grade | Typical Mark Range | Percentage |

| 6 | 15-17 | 75-85% |
| 5 | 12-14 | 60-70% |
| 4 | 9-11 | 45-55% |
| 3 | 6-8 | 30-40% |
| 2 | 3-5 | 15-25% |
| 1 | 0-2 | 0-10% |
- Your IA grade contributes 20% to your final Math AI grade.
