Balancing school-based assessment evidence against exam performance
A student has strong school-based assessment results for Units 3 and 4: high marks on two analytical essays and a persuasive oral. Her trial exam performance is weaker, particularly on unseen listening and on questions requiring her to compare two texts. Her teacher must advise her on where to spend the final six weeks. The student argues that her SAC results show she already knows the content, so she should focus only on exam technique. She has 8 hours of study per week available and sits four other subjects. The final exam weighting is substantial relative to her SAC scores, which are already banked.
1. Evaluate the student's argument that her SAC results mean she should focus only on exam technique.

The argument has a true premise and a false conclusion. The premise is true: her SAC results are strong and already banked, so further polishing of essay writing yields little marginal gain.
The conclusion does not follow, for two reasons:
- The weak areas are not technique problems. Unseen listening and cross-text comparison are skill and stamina problems. Technique advice (timing, planning) helps only after the underlying skill is secure. Her trial weakness in comparison suggests she has not practised holding two texts in view at once, which is a practice deficit, not a strategy deficit.
- SAC conditions differ from exam conditions. Her SAC essays were on prepared texts with known prompts; the exam requires transfer to unseen material. Strong performance under prepared conditions does not certify performance under transfer conditions.
So the correct inference is the opposite of hers: because the SAC component is secure, the exam component deserves the marginal hour, and within it the weakest skills deserve it first.
2. She has 8 hours per week for six weeks. Propose an allocation and justify the priorities.

Total budget: 48 hours. A defensible allocation:
- Unseen listening: 14 hours. Highest priority because it is her weakest area and improves mainly through repeated exposure, not through reading advice. Short daily sessions beat one long weekly session.
- Cross-text comparison: 14 hours. Second priority; the skill is distinctive and cannot be picked up incidentally while doing single-text essays.
- Full timed practice under exam conditions: 10 hours. Two or three complete papers, to build stamina and reveal whether the listening and comparison work transfers under pressure.
- Review of errors: 6 hours. Non-negotiable; practice without review produces fluency in the same mistakes.
- Light maintenance of essay skills: 4 hours. Enough to keep the strength from decaying, not enough to crowd out the weak areas.
Justification: the allocation follows marginal return. Her strongest area gets maintenance only; her weakest areas get the bulk. The review block is included because the trial-exam errors are the most informative data she has, and they are wasted if not analysed.
