GCE O/L Geography common mistakes
GCE O/L Geography · Understand the traps and how to avoid them.
When asked to explain why an earthquake occurs, the candidate writes only 'because plates move' or 'because of plate boundaries' and stops there, without naming the plate type, the direction of movement, or the faulting process.
Command words are misread: 'explain' is treated as 'state'. Candidates memorise the phrase 'plate movement' as a complete answer and do not rehearse the chain of reasoning (convection currents → plate motion → convergent/divergent/transform boundary → friction and pressure build-up → sudden release along a fault → seismic waves).
What to do instead
Practise building 4-step causal chains for each tectonic process and write them out as numbered arrows before writing prose. For a convergent boundary: two plates move towards each other → denser oceanic plate subducts → friction locks the fault → pressure releases suddenly → focus → seismic waves → epicentre. Check that the finished answer contains at least as many causal links as the mark tariff, since each mark usually rewards a distinct step.
In climate questions, candidates describe weather rather than climate, or give a single reason for a rainfall pattern without linking it to pressure belts, prevailing winds, relief or distance from the sea.
The weather/climate distinction is understood in class but not applied under exam pressure, and candidates default to the one factor they remember (usually 'it is near the equator') rather than selecting the factor the question actually targets.
What to do instead
Before answering, underline whether the question says weather or climate and the timescale implied. Then use a fixed factor checklist - latitude, altitude, distance from sea, ocean currents, prevailing winds, relief, pressure belts - and explicitly name which two or three apply and why the others do not. For rainfall, state the mechanism (convectional, relief, frontal) and then the location conditions that produce it.
On population questions, candidates quote a birth rate or a population figure without units or per-year basis, and interpret a population pyramid by describing its shape ('it looks like a triangle') instead of reading the age and sex structure.
Candidates learn the visual appearance of pyramids but not how to extract data from the bars, and they drop units because they copy figures straight from a table without recording what the figure measures.
What to do instead
Always attach the unit and basis to every statistic (for example births per 1,000 people per year, or persons per square kilometre). For pyramids, practise the three standard readings: width of the base (birth rate), steepness of the sides (death rate and life expectancy), and the bulge position (dependency or migration history). Write one sentence per reading, each anchored to a specific bar or age band.
When describing a settlement pattern on a map, candidates write 'it is scattered' or 'it is nucleated' without giving grid references, without distinguishing the pattern from the site, and without explaining the physical or human reason for it.
Settlement terms are memorised as labels rather than as evidence-based conclusions, and candidates confuse pattern (dispersed, nucleated, linear) with site (valley floor, hilltop, bridging point) and with function.
What to do instead
Use a three-part sentence structure: pattern + location evidence + reason. For example: 'Settlement is nucleated around grid reference 4523, where two roads meet at a bridging point, because the river crossing and route junction concentrate buildings.' Before writing, separate your notes into three columns - pattern, site, function - so the answer addresses the term the question uses.
On economic activity questions, candidates classify an activity by its label rather than its process, for example calling quarrying or fishing 'secondary' or treating tourism as a single sector, and they fail to explain locational factors for industry.
The four-sector model is learned with a few stock examples, so unfamiliar examples are forced into the wrong category. Locational factors are listed generically ('raw materials, labour, market') without being tied to the specific industry named in the question.
What to do instead
Classify by what happens to the material: extraction = primary, processing or manufacture = secondary, a service = tertiary, information or research = quaternary. Apply this test to the exact example in the question. For location, name the industry's weight-losing or weight-gaining character and then select the two or three factors that actually explain its siting, dismissing the others explicitly.
In development questions, candidates use a single indicator such as GDP per capita as if it measured development, and they treat the development gap as a purely natural or purely historical outcome without acknowledging both.
Single-figure comparisons are easy to remember and produce confident-sounding answers, and the multi-dimensional nature of development is under-rehearsed. Candidates also reproduce a simple 'rich North, poor South' narrative instead of causal explanation.
What to do instead
Keep a working set of complementary indicators - income per capita, life expectancy, literacy, infant mortality, access to clean water, HDI - and in any evaluation question state one strength and one limitation of each indicator you cite. For the development gap, structure the answer under physical, historical, economic and political headings and give one concrete mechanism under each.
On map skills, candidates measure distance along a straight line when the route is curved, give a bearing in the wrong direction (back-bearing), or read a grid reference with the eastings and northings reversed.
The procedures are known but performed in the wrong order under time pressure, and candidates do not check the direction of a bearing against the map. Curved-route measurement requires marking the route in stages, which is skipped.
What to do instead
Adopt fixed routines. Grid references: 'along the corridor, then up the stairs' - eastings first. Bearings: place the protractor at the start point, measure clockwise from north, and sanity-check that the result matches the compass direction you can see on the map. Route distance: lay the straight edge of paper along the route, mark each bend, then compare the total against the scale bar. Practise each routine on three different maps until it is automatic.
In fieldwork and data-analysis questions, candidates describe what a graph shows ('the bar for 2010 is higher') without quoting values, identifying the trend, or offering a limitation of the method used to collect the data.
Candidates treat graph reading as description rather than analysis, and they have not practised the language of trend (increase, decrease, peak, plateau, anomaly) or the standard limitations of sampling, sample size, timing and instrument error.
What to do instead
Use a data-commentary frame: quote the highest and lowest values with units, state the overall trend, identify any anomaly, then suggest one cause and one limitation. For fieldwork evaluation, keep a bank of limitations - small sample, unrepresentative site, single survey time, subjective measurement, recording error - and always pair a limitation with a specific improvement.
When asked to compare two places, regions or management strategies, candidates write two separate descriptions and never make an explicit comparison, so no comparative marks are earned.
The command word 'compare' is read as 'describe both', and candidates run out of time after describing the first case, leaving the second thin and the comparison absent.
What to do instead
Use paired sentence structures: 'whereas', 'compared with', 'both ... but'. Allocate equal time to each case and reserve a final sentence for the judgement the question demands. Before writing, draw a two-column table with the comparison criteria as rows so that every paragraph covers both cases on the same criterion.
In evaluation and sustainability questions, candidates list advantages and disadvantages but never reach a conclusion, or they use 'sustainable' as a synonym for 'good' without defining it in terms of environmental, economic and social costs and benefits.
Evaluation is the highest-order skill and is often left until last, so it is cut when time runs short. The three-pillar meaning of sustainability is recalled vaguely and not applied to the specific scheme in the question.
What to do instead
Plan for evaluation from the start: write the conclusion first in note form, then select evidence that supports it. Define sustainability explicitly as meeting present needs without compromising future needs, and test the scheme against environmental, economic and social criteria in turn. Finish with a justified judgement that names the criterion you weighted most heavily and why.
