Criteria Feedback
- The student communicates a focused and biologically relevant topic with clear scientific context.
- The student's research question is explicit, measurable, and appropriately framed for a secondary-data investigation.
- The student explains why the chosen population and outcome measures are relevant to the investigation.
- The student shows awareness that some study-design choices were made to improve comparability.
- The student's explanation sometimes implies that MRI volume changes directly prove neurogenesis.
- The student's method is less convincing where it combines heterogeneous studies into a single comparison.
- Some inclusion criteria are not applied consistently across all of the evidence the student uses.
- A few selection and standardisation choices need clearer justification to show why they are methodologically sound.

B.2Use of terminology and concepts
Good
Criteria Feedback
- The student uses a substantial range of relevant source material to support the investigation.
- The student applies biological terminology such as VO₂max, MRI, hippocampal subfields, and neuroplasticity with reasonable control.
- The student organises evidence in a way that helps the reader follow the scientific discussion.
- The student makes a genuine effort to connect structural findings with broader biological mechanisms.
- Some evidence is used too confidently, especially where values are estimated or where comparisons are not fully verified.
- The student sometimes describes markers such as BDNF or NAA as if they directly prove neurogenesis or plasticity.
- A few terms and concepts are not distinguished as carefully as they should be, especially between correlation, structural change, and underlying mechanism.
- The use of source material is relevant overall, but not always fully effective in the way the findings are interpreted.
