Preparation tips

  • Focus your first weeks on the highest-weight syllabus areas — they account for over half the marks and offer the fastest return on study time.
  • Use active recall with timed question sessions rather than passive re-reading. The ABS-CGSO written component rewards speed and precision under pressure.
  • Cross-reference every question explanation with the cited guideline section. Over a 3–6 month preparation cycle, this builds the mental index examiners expect in the oral component.
