Criterion E ("Use of Mathematics") is often misunderstood by students. It is not just about using complex formulas—it is about the sophistication, depth, and relevance of the mathematics you choose to engage with.
What Counts as "Sophisticated"?
Sophistication does not necessarily mean using university-level mathematics. It means using IB-level mathematics in a way that shows deep understanding. For example, using calculus to optimize a real-world scenario, rather than just memorizing the derivative rules.
Common Mistakes
- Choosing a topic that is too simple for your math level
- Over-relying on technology without showing understanding
- Failing to explain why you chose particular mathematical techniques
- Not connecting the mathematics back to your research question
Tip: Personal engagement is key. Choose a topic you genuinely care about, and your mathematical exploration will naturally be more sophisticated.
