A.3Research methodology
Excellent
Criteria Feedback
- You communicate a clear, focused research question and keep the investigation tightly connected to the stated aim.
- Your method is coherent and appropriately chosen, with a logical progression from theory to numerical modelling to experimental comparison.
- You show strong control of the topic by using a dimensionless parameter to organize the discussion and keep the comparison consistent.
- A few methodological details could be explained more explicitly so the investigation feels fully reproducible.
- The scope is well controlled, but the conditions under which your findings apply could be stated more sharply.
- Some wording is slightly imprecise in places, which weakens the precision of the framing.

Excellent
Criteria Feedback
- You demonstrate strong subject knowledge through accurate use of advanced mathematical and physical ideas.
- Your terminology is mostly precise and consistently tied to the modelling work.
- You apply the concepts to your own investigation rather than leaving them as isolated theory.
- A few mechanical interpretations need more careful qualification to stay fully accurate.
- Some terminology is slightly imprecise, especially where flexibility, elasticity, and state-variable meaning are discussed.
- You sometimes imply more certainty than the evidence directly supports.
