When asked to explain a landform such as a waterfall or oxbow lake, the candidate describes what the feature looks like or labels its parts instead of sequencing the processes that formed it.
Revision notes and diagrams often present the finished landform with labels, so candidates memorise the appearance rather than the erosion and deposition sequence; exam verbs like 'explain' are read as 'describe'.
What to do instead
Practise writing process chains with connectives ('plunge pool deepens → undercutting → cap rock collapses → retreat upstream') and check every sentence names a process (hydraulic action, abrasion, deposition) and a cause. Convert each labelled diagram in your notes into a numbered sequence of at least four steps before revising it.
When interpreting a climate graph or a cross-section, the candidate reads values off the wrong axis or quotes a figure without units or a time reference (e.g. 'rainfall is 50' rather than '50 mm in July').
Dual-axis graphs and cross-sections require switching between scales; under time pressure candidates grab the nearest number and omit units, losing precision marks even when the trend is correct.
What to do instead
Use a fixed reading routine: state the axis, the value, the unit and the month/place in one sentence before interpreting. On every practice graph, annotate the axes and units first, then write three data-quoting sentences using the pattern 'X is [value][unit] in [month/place], compared with [value][unit] in [other month/place]'.
In fieldwork questions the candidate describes the method ('we measured pebbles') but cannot justify the sampling strategy, identify a source of error, or say how the method could be improved.
Fieldwork is often taught as a trip to complete rather than an enquiry to evaluate, so candidates recall equipment but not the reasoning behind systematic versus random sampling or the difference between accuracy and reliability.
What to do instead
For each technique you have used, prepare a three-line card: why this sampling method suits this hypothesis, one specific inaccuracy (e.g. pebble size measured by eye rather than callipers), and one concrete improvement (same observer, random number table, larger sample). Rehearse phrasing that distinguishes 'unreliable' (few samples) from 'inaccurate' (poor measurement).
Population and development answers use unsupported generalisations such as 'LEDCs have high birth rates because they are poor' without naming a model, indicator or mechanism, or without using the data provided.
These topics invite opinion, and candidates default to everyday assumptions; they also memorise the shape of the demographic transition model but not the reasons for each stage.
What to do instead
Attach every claim to a named framework or indicator (DTM stage, population pyramid shape, infant mortality, GNI per capita, HDI) and to a mechanism (child mortality, education of women, mechanised agriculture, pensions). Build a table of DTM stages with two causes and two consequences each, and in practice answers quote at least two figures from the stimulus.
In rivers and coasts questions the candidate confuses erosion processes (hydraulic action, abrasion, attrition, solution) with transportation processes (traction, saltation, suspension, solution), or mislabels a landform as erosional when it is depositional.
The two lists share the term 'solution' and are learned together as vocabulary rather than as parts of a system, so recall collapses under exam pressure.
What to do instead
Learn them in contrasting pairs tied to energy conditions: high energy and steep gradients favour erosion and traction; low energy and gentle gradients favour deposition and suspension. Sort a mixed list of twelve processes and landforms into erosional/depositional and river/coast columns without notes, and explain each placement in one clause.
Climate change answers list 'global warming is bad' consequences without distinguishing mitigation from adaptation, or without separating natural and human causes with evidence.
Textbooks present causes and impacts as a single block, and the command words 'mitigate' and 'adapt' look interchangeable to candidates who have not practised using them.
What to do instead
Keep two columns: actions that reduce emissions (renewables, afforestation, carbon pricing, transport policy) and actions that reduce vulnerability (sea defences, drought-resistant crops, early warning, water storage). For causes, cite the specific evidence (ice-core CO2 record, isotope ratios, timing of warming versus industrialisation) that distinguishes human from natural forcing.
Map-reading answers give a four-figure grid reference when a six-figure one is required, or measure straight-line distance instead of following the road or river, and omit the compass direction.
The 'along the corridor, up the stairs' rule is known but applied carelessly under timing pressure, and candidates do not check whether the question asks for location, distance along a feature, or bearing.
What to do instead
Adopt a checking habit: state eastings before northings, count to the nearest tenth of a square for six figures, and re-read the question to see whether it says 'straight line' or 'along the road'. For distance along a route, lay a strip of paper along the feature, mark the turns, then measure against the scale bar and give the answer in km with the direction.
Ecosystem and biome answers describe the climate and vegetation of a tropical rainforest or savanna but cannot explain the links between them (nutrient cycling, leaching, canopy structure, adaptations), treating the biome as a list of facts.
Biomes are frequently revised as descriptive case studies with pictures, so candidates never practise tracing cause and effect through the system.
What to do instead
Draw the nutrient cycle for each biome with labelled flows (litterfall, decomposition, uptake, leaching, runoff) and annotate each arrow with the climate condition driving it. For each biome write three adaptation–condition pairs (e.g. drip tips and high rainfall, buttress roots and thin soils, waxy leaves and drought) so description always carries an explanation.
Urban and economic questions ask for a case study, and the candidate names a city or industry but supplies no specific locational, quantitative or change-over-time detail, so the answer could apply anywhere.
Case studies are memorised as names and a few adjectives rather than as evidence banks, and candidates do not realise that marks depend on precise, place-specific facts.
What to do instead
For each case study keep a five-line evidence card: location and national context, two figures (population, jobs, migration, land values), one named scheme or policy, one group who benefited and one who did not, and one change over time. Rehearse inserting two of these facts into any 6- or 8-mark answer so the place is unmistakable.
In GIS and data-interpretation questions the candidate describes what a map or graph shows layer by layer without stating the overall pattern, the anomaly, or a limitation of the data source.
Candidates read displays literally and have not been taught the describe–interpret–evaluate structure that higher-mark questions reward.
What to do instead
Answer in three moves: an overview sentence naming the general pattern, two specific data points including any anomaly, then one evaluative comment (scale, date of imagery, sampling bias, choropleth shading by administrative area). Practise on any graph or layered map until the three moves become automatic.
