GCE A/L Geography common mistakes
GCE A/L Geography · Understand the traps and how to avoid them.
When asked to explain a landform such as a spit, an arch or a waterfall, the candidate describes the sequence of processes (e.g. longshore drift, hydraulic action) without actually linking each process to a change in the shape of the landform, so the answer reads as a process list rather than a landform explanation.
Textbooks and revision guides present processes and landforms in separate sections, so candidates memorise two lists and reproduce both, assuming the examiner will connect them. Under time pressure they write the process list first and run out of time before adding the landform link, not realising the link is the mark-earning element.
What to do instead
Practise a fixed sentence pattern for every landform answer: 'Process X removes material from point A, which causes the feature at point B to become [shape], and this continues until [end point].' Write one such chain for each of six named landforms per topic (e.g. headland-bay, wave-cut platform, spit, salt marsh, corrie, arete) and self-mark by checking that every process sentence names a landform part and a direction of change.
The candidate uses case-study material as decoration: a named example is dropped into an answer (e.g. 'as in Bangladesh') without any specific data, dates, named locations within it, or explicit comparison with the question's concept, so it earns no application marks.
Candidates learn one case study per topic as a story and assume mentioning the name is enough, because in class discussion the detail was supplied verbally by the teacher. They also fear getting figures wrong, so they keep the example vague, which is precisely what loses the marks.
What to do instead
Build a one-page case-study card per example with six fixed slots: location at two scales, two dated figures, one named sub-location, the process or policy mechanism, one limitation of the example, and one contrast case. In practice answers, force yourself to use at least three slots with numbers and check each against the question wording before moving on.
In hydrology and water-security questions, the candidate confuses stores and flows, or uses terms such as 'infiltration', 'percolation', 'throughflow' and 'groundwater flow' interchangeably, and describes a storm hydrograph without distinguishing the rising limb, peak and recession and the processes operating at each stage.
The water cycle is taught as a labelled diagram, and candidates reproduce the labels without attaching a direction, a medium (soil versus rock) or a timescale to each term. The vocabulary looks similar, so the confusion survives unnoticed until an examiner asks for a causal sequence.
What to do instead
Redraw the drainage-basin diagram from memory with arrows and add three annotations to every arrow: medium, speed, and what increases or decreases it. Then take one storm event and write a paragraph per hydrograph stage naming the dominant flow at that moment. Test yourself by covering the labels and re-annotating.
When a question gives data (a table, a graph, a map or a photograph description) and asks for analysis, the candidate describes the pattern ('it goes up', 'there is a cluster in the north') and stops, without offering a mechanism, a comparison of rates, an anomaly, or a judgement about reliability.
Candidates treat data questions as comprehension rather than analysis, and they have often been trained to 'describe then explain' as two separate steps, so they spend the whole answer on description. They also avoid commenting on anomalies because they think it shows they do not understand the data.
What to do instead
Use a three-move structure for every data response: quantify the pattern with at least two figures or rates, identify the most significant anomaly or exception and explain it, then state what the data cannot tell you. Practise on past-paper-style tables until the three moves take under four minutes.
In glacial and periglacial answers, the candidate describes a process such as abrasion or freeze-thaw weathering as if it were a landform, or explains a landform using a process that cannot operate in that environment (e.g. explaining a roche moutonnée by freeze-thaw alone, or describing periglacial patterned ground as glacial deposition).
Glacial and periglacial processes are visually dramatic and easy to remember as a list, while the landforms are less familiar, so candidates substitute the process they know for the landform they do not. Periglacial environments in particular are under-taught, so candidates borrow glacial explanations.
What to do instead
Make a two-column table for each environment: process on the left, landform it produces on the right, with a one-line mechanism in the middle. For every landform, write the sentence 'This cannot be formed by X because...' to rule out the wrong process. Check each answer against the environment named in the question before writing.
The candidate evaluates a fieldwork investigation only in terms of 'human error' and 'equipment error', or claims the method was 'accurate because we used a quadrat', without linking the sampling strategy, sample size, timing or spatial coverage to the reliability and validity of the conclusion drawn.
Textbook evaluation checklists list 'accuracy, reliability, validity' as words to use, and candidates learn the words without learning what each one refers to in their own data. They also lack practice in articulating what a different sampling method would have changed.
What to do instead
For each fieldwork method you have used, write three sentences: one on precision (what the instrument or category could and could not resolve), one on representativeness (sample size, stratification, when and where you sampled), and one on what conclusion the data can and cannot support. Rehearse by re-evaluating a classmate's dataset, not just your own.
In urban and population questions, the candidate answers with a model or theory (the demographic transition model, the Burgess concentric zone model, the urban heat island) as if it were evidence, without naming a real place, a date, or data, and without acknowledging where the model fails to fit.
Models are memorable and give a reassuring structure, so candidates use them as a substitute for case-study knowledge. Because the model is 'correct' in the abstract, they do not notice that the question asks about a specific place or process, and the answer becomes unfalsifiable.
What to do instead
Adopt a rule: every model mention must be followed by a named place and one sentence on fit or misfit ('the model predicts X, but in [city] Y occurs because...'). Prepare two contrasting urban or population examples with dated statistics, and practise inserting the model as a lens on the example rather than as the answer itself.
The candidate treats globalisation, trade and development as synonyms and writes development answers that measure development only by GDP per capita, ignoring composite indices, inequality, and the difference between economic growth and development, or attributes uneven development to a single cause.
Development is taught through headline indicators and dramatic case studies, and candidates latch onto the single most memorable statistic. The terminology overlap between globalisation, trade and development encourages loose use, and candidates do not realise that the command word 'assess' requires weighing multiple causes.
What to do instead
Learn three indicators by name with what each measures and one limitation: GDP per capita, the Human Development Index, and the Gini coefficient. For any development question, plan at least two causes at different scales (global trade rules, national policy, local access) and write one sentence weighing their relative importance. Check that 'growth' and 'development' are used correctly throughout.
In climate and atmosphere answers, the candidate mixes up the enhanced greenhouse effect with the natural greenhouse effect, or confuses causes of long-term climate change (orbital, volcanic, solar) with causes of recent warming (anthropogenic greenhouse gases), and describes feedbacks such as albedo change without stating the direction of the feedback.
The same vocabulary appears in both natural and enhanced contexts, and diagrams in textbooks look similar, so the distinction blurs. Candidates also memorise causes as a list without attaching a timescale, so they cannot sort them when the question asks about a specific period.
What to do instead
Build a timeline with three bands: millions of years, thousands of years, and the last 150 years, and place each cause in its band with a one-line mechanism. For each feedback, write 'increase in X leads to increase/decrease in Y leads to further increase/decrease in X' and state whether it amplifies or dampens. Test by explaining the same diagram twice, once for natural and once for enhanced.
The candidate writes long, general introductions and conclusions that restate the question, and then runs out of time before reaching the evaluative or case-study section, so the highest-tariff part of the answer is missing or truncated.
Candidates believe length signals effort and that an introduction is required, so they spend five minutes setting context. In timed conditions they do not plan, so the answer grows from the beginning rather than being allocated to the marks available, and the evaluative marks are lost.
What to do instead
Before writing, spend two minutes converting the command word and the marks into a plan with a fixed number of points and a judgement. Write the judgement sentence first in note form, then answer directly with no restating introduction, and time yourself so the evaluative paragraph is drafted by the two-thirds mark. Review one timed script and mark where the evaluative content fell.
