A scientific or graphical calculator that meets JCQ regulations may be used (some GCSE Mathematics and Science papers are non-calculator). Graphical calculators must be set to exam mode; you must clear any stored programs, notes or data before the exam, and the calculator must not be able to retrieve stored text or formulae.
AO1: Demonstrate knowledge of locations, places, environments, processes, and concepts (AO1) (25%)
AO2: Demonstrate understanding of real-world geographical case studies, concepts, and processes (AO2) (25%)
AO3: Apply knowledge and understanding to interpret, analyse, and evaluate geographical information and issues (AO3) (25%)
AO4: Select, adapt, and use a variety of skills and techniques to investigate questions and issues (AO4) (25%)
根據歷屆試題與評分準則整理（2022–2024）。
計算機程式
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
用途: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使用時機: Solving or sketching a function when you want to find where its graph crosses or turns.
步驟
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
用途: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使用時機: Any data-handling, statistics, or required-practical analysis question.
步驟
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
用途: Keep full-precision intermediate values to avoid rounding errors.
使用時機: Multi-step calculations where premature rounding loses the final accuracy mark.
步驟
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
用途: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使用時機: As a check only, after solving by hand.
步驟
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
常見錯誤
1high涉及分數: 6Case Studies
Failing to include place-specific details in high-tariff 12-mark case studies (e.g., specific dates, locations, figures, and facts), which caps the answer at Level 2.
如何避免: Use precise named facts (e.g., 'Swanage in Dorset, Old Harry's Wife stump, 12m high' or 'The Big Dry drought in Australia 2002-2009, 10,000 cotton jobs lost') to demonstrate comprehensive knowledge.
2high涉及分數: 3Landscapes of the UK
Using general, vague words like 'erosion' or 'weathering' in physical geography without naming or explaining the specific physical mechanisms.
如何避免: Specify the exact process at work, such as hydraulic action, abrasion, attrition, solution, or freeze-thaw weathering, detailing how the mechanism operates.
3medium涉及分數: 2UK Environmental Challenges
Confusing the direction 'from' which a wind or ocean current travels with the direction 'to' which it is heading.
如何避免: Remember that winds and currents are named after the direction they come FROM (e.g., North Atlantic Drift brings warm tropical water from the southwest toward the UK, keeping winters mild).
4high涉及分數: 8Geographical Fieldwork
Writing about physical geography fieldwork methods (e.g., river measurements or pebble shape) in a human geography fieldwork question, or vice versa, completely invalidating the answer.
如何避免: Always carefully read the header of the fieldwork section to check if it asks for your 'human geography' or 'physical geography' investigation before starting to write.
5medium涉及分數: 4Extended Essays
Omitting a clear, structured, and justified conclusion in 'To what extent...' or 'Evaluate...' essay questions.
如何避免: Explicitly state your level of agreement (e.g., 'To a large extent...') in your final paragraph and justify it based on the evidence presented in the body of your essay.
6medium涉及分數: 2Geographical Skills
Omitting clear mathematical workings or failing to round exactly to the requested number of decimal places in statistical calculation questions.
如何避免: Always write out your mathematical steps (e.g., 'change / original x 100') and check if the question asks for one or two decimal places before writing your final answer.
7medium涉及分數: 2People of the UK
Suggesting unsustainable strategies, such as building more road lanes or constructing new roads, when asked for sustainable strategies to overcome urban challenges.
如何避免: Suggest sustainable strategies that have environmental longevity, such as expanding public electric tram systems, implementing park-and-ride schemes, or using solar panels on housing.
8medium涉及分數: 1Geographical Skills
Providing 6-figure grid references when the question explicitly requests a 4-figure grid reference, or vice versa.
如何避免: Read map coordinate instructions carefully. A 4-figure coordinate identifies a whole square, whereas a 6-figure coordinate pinpoints an exact point within a square.
