What the exam covers
We don't have past-paper frequency data for this exam, so here is the course, module by module. Make sure every module is covered.
Night-before and exam-morning checklists
The night before
- Check the start time of each exam; the 15-minute reading period is included in the timetable times.[2]
- Pack a transparent pencil case: pens, pencils, highlighters, erasers, sharpener and a ruler.[1]
- Pack your approved calculator and spare batteries (CAS only where allowed: General Maths, Methods Exam 2, Specialist Exam 2).[1]
- Still water in a clear plastic bottle, labels removed, no more than 1500 mL (it stays off your table).[1]
- Stop revising around 8 pm, set two alarms and sleep.[1]
Exam morning
- Eat a real breakfast.[1]
- Arrive at least 30 minutes before the start time.[2]
- If you are up to 30 minutes late you still get full writing time, but no reading time.[1]
- Leave phones, smart watches and fitness trackers outside the exam room.[1]
- In reading time: read and plan, but don't write or use your calculator.[1]
- You can't leave before 30 minutes of writing time or in the last 5 minutes.[1]

Unit 3: How can biodiversity and development be sustained?
From broadest to most specific: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Each level is nested inside the one above. A useful mnemonic is "Did King Philip Come Over For Good Soup."
Supporting (soil formation, nutrient cycling, primary production), provisioning (food, water, timber, medicine), regulating (climate, flood control, water purification, pollination) and cultural (recreation, tourism, spiritual value). Supporting services underpin all the others.
Habitat loss and fragmentation, Invasive species, Pollution, human Population pressure and Overexploitation are the leading drivers of biodiversity loss, with climate change amplifying all of them. Habitat loss is generally the largest single driver.
Unit 4: How can climate change and energy use be managed?
Eccentricity (orbit shape, about 100,000 years), obliquity (axial tilt, about 41,000 years) and precession (axial wobble, about 26,000 years). They change the timing and distribution of solar energy, triggering glacial and interglacial cycles, then feedbacks amplify the change.
A carbon source releases more carbon than it absorbs (burning fossil fuels, deforestation, respiration). A carbon sink absorbs more than it releases (growing forests, oceans, soils). The balance of sources and sinks sets the amount of carbon dioxide in the atmosphere.
Earth's climate system is the interaction of the atmosphere (gases), hydrosphere (water and ice), biosphere (living things) and lithosphere (rock and soil). Energy and matter (especially carbon and water) move continuously between them, so a change in one affects all.
Incoming shortwave solar radiation warms the surface; the surface re-radiates as longwave infrared; greenhouse gases absorb and re-emit this infrared, returning some to the surface. This natural process keeps Earth about 33 degrees Celsius warmer and habitable.
Unit 3: How can biodiversity and development be sustained?
In-situ keeps species and ecosystems in their natural home and lets natural selection continue; ex-situ removes them to zoos, sanctuaries or seed banks as an insurance population. In-situ is usually preferred; ex-situ is a safeguard.
Unit 4: How can climate change and energy use be managed?
Mitigation reduces or removes greenhouse gas emissions (switching to renewables, efficiency, reforestation, carbon pricing). Adaptation adjusts to changes already underway (sea walls, drought-tolerant crops, bushfire planning). Effective policy uses both.
Efficiency (%) = (useful energy output divided by total energy input) multiplied by 100
Non-renewable sources (fossil fuels, nuclear) are finite stores; fossil fuels also emit large amounts of CO2. Renewable sources (solar, wind, hydro, geothermal, biomass) are naturally replenished and low-carbon, but most are variable and depend on location.
