Criteria Feedback

The student clearly states a relevant investigation question and keeps returning to it throughout the essay.
The student shows an appropriate awareness of source selection and includes a range of research types.
The student's method shows genuine intention to be systematic, especially in the way they describe database use and source appraisal.

The question is still too broad for a tightly focused investigation.
The student's method is not fully reproducible because key details such as exact search strings, dates, and screening decisions are missing.
The link between the student's method and the final set of sources could be explained more transparently.

Criteria Feedback

The student demonstrates good subject knowledge and uses it in ways that generally support the inquiry.
The student uses a number of key terms accurately, including several that are central to genetics and performance physiology.
The student often connects biological mechanisms to the performance argument rather than simply defining terms.

At times the student phrases candidate-gene findings too strongly, which can make associations sound more deterministic than the evidence supports.
Some broad population-level claims need more careful qualification.
The student's terminology would be stronger if they distinguished more consistently between association, causation, and prediction.
