Week 1: take representative mixed sets, review the official formats and identify weak CPS areas and PD behaviours. Write three to five recurring error types rather than a long undifferentiated topic list.
Week 2: revisit those concepts in new scenarios and learn to explain why a tempting alternative is less appropriate. Keep both ranking and select-three PD practice active.
Week 3: increase timed mixed questions and monitor unanswered items separately from incorrect ones. If speed remains weak, find where time is lost rather than blindly accelerating every question.
Week 4: rehearse the full test if practical, repair the two or three most consistent errors, check logistics and rest. Four weeks may not be enough from a weak baseline; do not claim coverage simply because questions were clicked.
