Many students think IB Math AI exams are just about getting the right answer. They are not.
Examiners reward method, reasoning, and structure. That is why two students can get the same final number and still walk away with different marks.
IB marking system
- M marks for method
- A marks for answer or accuracy
- R marks for reasoning or interpretation
Why you lose marks
Even when your final answer is correct, you can still lose marks:
- No working means you lose method marks
- No explanation means you lose reasoning marks
- Poor structure makes it harder for the examiner to reward you
Weak presentation
x = 5
Stronger presentation
Using the formula ..., x = 5
The key insight
IB rewards:
- Clear steps
- Structured answers
- Explanations that match the question
The difference between a 5 and a 7 is often not knowledge. It is how clearly you present the knowledge you already have.
