How to Use the IB Math Grade Calculator
If you have ever wondered where you stand in IB Mathematics, you are not alone. Every year, thousands of students try to figure out their predicted grades before results day. That is exactly why we built this calculator to give you a clear, accurate picture based on the official IB grading system.
Understanding Weighted Percentages
Here is something many students do not realize your IB Math grade is not just a simple average. The IB uses a weighted percentage system, which means each component of your assessment contributes differently to your final score.
For Standard Level (SL), your two exam papers carry equal weight at 40% each, while your Internal Assessment makes up the remaining 20%. Higher Level (HL) works differently as Papers 1 and 2 each count for 30%, Paper 3 adds another 20%, and the IA still holds that crucial 20%.
| Component | SL Weight | HL Weight |
|---|---|---|
| Paper 1 | 40% | 30% |
| Paper 2 | 40% | 30% |
| Paper 3 | — | 20% |
| Internal Assessment | 20% | 20% |
Math AA vs Math AI Which One Are You Taking?
Analysis and Approaches (AA) is the more traditional route. If you enjoy algebra, calculus, and mathematical proofs, this is your course. It is particularly suited for students heading into mathematics, physics, engineering, or computer science.
Applications and Interpretation (AI) takes a different approach. It focuses on statistics, mathematical modeling, and real world problem solving. If you are interested in social sciences, business, psychology, or biology, AI might be the better fit.
About Grade Boundaries
Grade boundaries shift from session to session depending on exam difficulty. For the May 2025 session, you will need roughly 65 to 66% to secure a Grade 7 in Math AA SL, while AA HL requires around 71 to 73%. These thresholds ensure fairness across different exam years.
