When asked to explain why a named location has a particular climate, candidates describe the climate (temperature and rainfall figures) instead of explaining the causal factors, and omit latitude, altitude, distance from the sea, prevailing winds, ocean currents and relief.
The command word 'explain' is treated as 'describe', and candidates reproduce remembered climate statistics rather than linking each statistic to a controlling factor, often because they have memorised data but not the underlying atmospheric processes.
What to do instead
Before writing, underline the command word and build a two-column plan: 'feature' and 'because'. Force every sentence to contain a causal connector ('because', 'this leads to', 'as a result of'). Practise converting a climate description into an explanation by adding one controlling factor to each fact, and check that at least four distinct factors (latitude, altitude, continentality, winds/currents, relief) are used where relevant.
Candidates label a diagram of a frontal depression or the general circulation with correct terms but describe weather changes in the wrong order, or claim warm air rises over cold air at a warm front without linking the sequence of cloud, pressure and precipitation to the passage of each front.
Surface weather symbols are memorised as isolated labels rather than as a sequence of events, so candidates cannot connect the approaching warm sector, the passage of the warm front, the cold front and the returning cold sector into a temporal narrative.
What to do instead
Draw an annotated cross-section from memory weekly, writing beside each stage what happens to pressure, cloud type, precipitation and temperature. Then write a timeline ('before, during, after') for a named mid-latitude depression and self-test by covering the labels.
On landform questions, candidates name a process (e.g. hydraulic action, freeze-thaw, mass movement) but cannot say where on the landform it operates, at what scale, or how it produces the specific shape asked about, so answers describe a generic river or coast rather than the feature named in the question.
Landform knowledge is learned as a list of processes and a separate list of features, without a mental model linking process, location on the profile and resulting form; candidates also confuse erosion, transportation and weathering terminology.
What to do instead
For each major landform (waterfall, meander, oxbow, spit, corrie, arete, drumlin), write a three-step chain: process → location/conditions → resulting form. Practise annotating a blank cross-profile with processes at each point, and use precise verbs (abrasion, attrition, solution, plucking) rather than 'erosion' alone.
In tectonics answers, candidates describe the effects of an earthquake or volcano (deaths, damage, aid) when the question asks about causes, distribution or plate boundary processes, and they mix up conservative, constructive and destructive boundaries and their associated hazards.
Case-study detail is over-rehearsed and plate-boundary mechanics under-rehearsed, so under time pressure candidates default to the vivid case study they remember rather than answering the process question actually set.
What to do instead
Build a boundary matrix (divergent, convergent oceanic-continental, convergent continental-continental, transform) with columns for plate movement, landforms, hazard type and an example. Answer past questions in plan form only, checking that the plan addresses the command word before writing prose.
On ecosystem and soil questions, candidates describe the characteristics of a biome or soil profile but do not explain the flows and stores (nutrient cycling, decomposition rates, leaching, humification) or link them to climate and vegetation, and they confuse soil horizons or processes such as podsolisation, gleying and laterisation.
Biomes are learned as descriptive lists of plants and animals, and soil profiles as a memorised colour diagram, without the underlying transfers of energy and matter that the syllabus expects candidates to trace.
What to do instead
Draw a nutrient-cycle and a soil-profile diagram side by side and annotate each store and transfer, then write one sentence per horizon stating what process created it. Match each soil process to the climate that drives it and test yourself by naming the process from a climate description alone.
In population answers, candidates quote a model (Demographic Transition Model, population pyramids, Ravenstein) by name and shape but cannot explain what drives the change between stages, apply it to a specific country, or evaluate its limitations.
Models are memorised visually as 'the DTM shape' rather than as an explanatory framework, and candidates have not practised applying a model to unfamiliar data or criticising its assumptions.
What to do instead
For each stage of the DTM, write the birth-rate and death-rate drivers (economic, social, medical, cultural). Then take a named country and justify its stage with two pieces of evidence. Finally list two limitations of the model (e.g. it assumes a single pathway, ignores migration).
On economic activity and development questions, candidates describe what a development indicator measures but do not compare indicators, explain why they diverge (e.g. GDP per capita versus HDI or Gini), or link the location of an industry to its inputs, transport and market in a changed global context.
Development is treated as a single number rather than a contested, multidimensional concept, and industrial location theory is learned as a static list of factors rather than as a set of changing cost surfaces.
What to do instead
Create an indicator comparison table: what it measures, what it misses, one country where it misleads. For industry, take one sector (e.g. car manufacturing or call centres) and justify its location using named factors, then explain how globalisation or technology has shifted those factors.
In urbanisation and rural change answers, candidates describe land-use models (Burgess, Hoyt) or rural change as static patterns, without explaining the processes (counter-urbanisation, gentrification, rural diversification, land reform) or evaluating the social and environmental consequences for different groups.
Models are drawn as diagrams to be reproduced rather than as idealised patterns to be tested against real cities, and candidates have not practised the 'who gains, who loses' evaluation that higher-mark questions reward.
What to do instead
For each model, write two ways a named city departs from it and why. For each process, produce a short stakeholder table (residents, businesses, government, environment) with gains and losses, and practise turning that table into an evaluative paragraph.
On resource-management questions, candidates list environmental problems (deforestation, water scarcity, pollution) without explaining the management strategies, their scale, their trade-offs or why they succeed or fail, and they ignore the 'people versus environment' interaction the question asks about.
Environmental issues are learned as a catalogue of problems, and management is reduced to a list of solutions without considering cost, governance, equity or unintended consequences.
What to do instead
For each resource issue, build a four-part frame: cause → impact on people and environment → management option at local/national/global scale → evaluation of that option. Practise writing one evaluation sentence per strategy using criteria such as cost, equity and sustainability.
In skills and fieldwork questions, candidates read a graph or map but do not state units, axes, scale or direction, misread choropleth shading and isolines, and describe a fieldwork method without justifying sampling strategy, sample size, controls or how the data were analysed and how reliable they are.
Graph and map interpretation is treated as a reading exercise rather than a precise extraction of data, and fieldwork is memorised as a procedure rather than as an enquiry with decisions about sampling, accuracy and limitations.
What to do instead
Adopt a fixed reading routine: title, axes and units, trend, anomalies, then conclusion. For fieldwork, write a one-page enquiry plan with hypothesis, sampling method and justification, equipment, risk, presentation technique, statistical test and two limitations with improvements. Practise extracting three specific figures from a graph before writing any interpretation.
