Birth Rate
Per 1000 people per year. Always state 'per 1000'.
Birth rate = (live births ÷ total population) × 1000 Cambridge O Level 2217

O Level Geography — Calculations, Skills and Named Examples
Cambridge O Level Geography (2217) rewards three things students often neglect: the handful of calculations that appear every year, precise map and graph skills on Paper 2, and specific named case studies with real figures. This reference sheet collects all three.
🔢
Every calculation on the syllabus, with units
🗺️
Map skills — grid references, scale, cross-sections
📊
Case study framework with the detail examiners want
🔑
Command word guide and mark-tariff timings
Population Calculations
These appear in some form on almost every Paper 1. Learn the units — a rate without its unit loses the mark.
Death Rate
Per 1000 people per year.
Death rate = (deaths ÷ total population) × 1000 Natural Increase Rate
Natural increase = birth rate − death rate As a percentage: (birth rate − death rate) ÷ 10
A negative value is natural decrease
Population Density
People per km². Watch for areas given in hectares or m².
Population density = total population ÷ land area Infant Mortality Rate
Per 1000 live births — the denominator is births, not total population.
IMR = (deaths under age 1 ÷ live births) × 1000 Dependency Ratio
A high ratio means a small working population supporting many dependants.
Dependency ratio = ((under 15) + (over 64)) ÷ (15–64) × 100 Doubling Time
The 'rule of 70'. Useful for comparing growth scenarios.
Doubling time (years) ≈ 70 ÷ annual growth rate (%) Map and Graph Skills (Paper 2)
Paper 2 is almost entirely skills. These are mechanical marks — they are the cheapest marks on the whole qualification.
Four-Figure Grid Reference
Identifies a 1 km square. Eastings first, then northings.
Read ALONG the bottom (eastings), then UP the side (northings)
Mnemonic: along the corridor, up the stairs
Six-Figure Grid Reference
Identifies a point within a square by dividing each side into tenths.
Never put a space or comma in the middle. Write it as six continuous digits.
Easting (2 digits) + tenths (1 digit), then northing (2 digits) + tenths (1 digit)
Estimate tenths by eye — no ruler needed
Measuring Distance with Scale
Straight line: measure in cm, multiply by the scale
1:50 000 → 1 cm = 0.5 km
1:25 000 → 1 cm = 0.25 km
Curved route: use the edge of paper, pivoting at each bend
Bearings
Measured clockwise from grid north
Always write three digits: 045°, not 45°
Place the protractor centre on the start point
Gradient
Gradient = vertical change ÷ horizontal distance Express as 1 in n — divide horizontal by vertical
Keep both in the same unit (metres) before dividing
Cross-Section Technique
Lay paper along the section line, mark where each contour crosses
Transfer marks to graph paper, plotting height on the y-axis
Join with a smooth curve, never straight segments
Label the vertical exaggeration if asked
Describing a Distribution or Trend
The standard mark scheme shape for any 'describe the pattern' question.
Quoting data is almost always worth a mark on its own. Never describe a graph without numbers.
Overall pattern in one sentence
Quote figures with units from the resource
Name one anomaly or exception
Physical Geography Processes
Learn the sequence, not just the vocabulary. Most marks come from ordering a process correctly.
River Processes
Erosion: hydraulic action, abrasion, attrition, solution
Transport: traction, saltation, suspension, solution
Deposition: when velocity falls below the competence threshold
Coastal Processes
Longshore drift: waves at an angle → swash up-beach → backwash perpendicular
Headland sequence: crack → cave → arch → stack → stump
Constructive waves build beaches; destructive waves strip them
Weather Calculations
Diurnal temperature range = daily max − daily min
Annual temperature range = hottest month mean − coldest month mean
Mean monthly temperature = sum of daily means ÷ days in month
Relative humidity = (actual vapour ÷ saturation vapour) × 100
Plate Boundaries
'No volcanoes at conservative boundaries' is a commonly tested discriminator.
Constructive (divergent) — plates separate, new crust forms
Destructive (convergent) — subduction, deep trenches, explosive volcanoes
Conservative (transform) — plates slide past, earthquakes but no volcanoes
Collision — two continental plates, fold mountains
Case Study Framework
A case study without numbers and place names is a general answer. Build each one to this shape.
The Five Things Every Case Study Needs
Two figures you can actually recall beat ten you half-remember. Pick your numbers and drill them.
Place name and country — be specific, not 'a city in Asia'
A date
Two or three real figures (population, deaths, cost, hectares, %)
Causes — physical and human
Responses — short-term and long-term
Case Studies You Need Ready
One earthquake and one volcanic eruption
One tropical storm
One river flood and its management
One area of high and one of low population density
One example of rapid urban growth, with its problems
One industrial zone or manufacturing region
One tourist area, with impacts and management
One area of deforestation or desertification
One energy or water supply scheme
Contrasting LIC and HIC Responses
Many questions ask you to compare impacts or responses between richer and poorer countries. Prepare one pair.
Same hazard, different death toll — explain via preparedness and building standards
Compare monitoring, warning systems and insurance cover
Compare the speed and funding of reconstruction
Command Words and Mark Tariffs
Describe
What it looks like, where it is, how it is distributed. No reasons.
1 mark per point. No 'because'.
Explain / Give reasons for
Why. Each point needs a causal chain, not a single word.
Cause → process → consequence
Chain two links per mark on higher tariffs
Compare / Contrast
You must write about both items in the same sentence. Separate paragraphs on each score poorly.
Use comparative connectives. 'Whereas', 'while', 'compared to' are mark-bearing words here.
A is higher than B because…
Whereas A…, B…
Suggest
Apply your knowledge to an unfamiliar resource. There is no single right answer — reward comes from plausible, geographical reasoning.
Evaluate / To what extent
Two sides plus a judgement, exactly as in History. State which effects or measures matter most and why.
On the 7-mark extended questions, reserve the last two sentences for the judgement.
Timing Rule
Roughly one minute per mark, leaving five minutes at the end to check units and figures.
1-mark data read: 30 seconds
3-mark describe: 3 minutes
7-mark evaluate: 8 minutes including a one-minute plan
How to Use This Reference Sheet
Boost your Cambridge exam confidence with these proven study strategies from our tutoring experts.
🔢
Write the unit every time
'Per 1000', 'people per km²', '°C'. Unit-less rates are the most common avoidable loss on Paper 1 calculations.
🗺️
Paper 2 skills are the cheapest marks available
Grid references, scale and cross-sections are mechanical. An hour of drilling them is worth more than an hour of re-reading notes.
📊
Quote data in every resource question
If a graph or table is printed, your answer should contain numbers lifted from it, with units. This is almost always explicitly credited.
📍
Drill three figures per case study
Not ten. Three numbers you can recall under pressure, plus the place name and date, is a complete case study for exam purposes.
⚖️
Reserve the last two sentences for judgement
On evaluate questions, consciously stop describing and start deciding. A labelled judgement is easy for an examiner to credit.

Knowing the reference sheet isn't the same as knowing how to answer
Most marks are lost to technique, not content — describing when the question says explain, missing the mark scheme trigger, or misreading the command word. The Exam Technique Cheat Sheet breaks down what each command word demands and what examiners actually reward, question type by question type.
