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: AO1: Demonstrate knowledge of locations, places, processes, environments and concepts (22.5%)
AO2: AO2: Demonstrate geographical understanding of concepts and interrelationships (27.5%)
AO3: AO3: Apply knowledge and understanding to interpret, analyse and evaluate geographical information (32.5%)
AO4: AO4: Select, adapt and use a variety of skills including quantitative and fieldwork skills (17.5%)
วัตถุประสงค์: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
ใช้เมื่อใด: Solving or sketching a function when you want to find where its graph crosses or turns.
ขั้นตอน
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
ใช้เมื่อใด: Any data-handling, statistics, or required-practical analysis question.
ขั้นตอน
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Keep full-precision intermediate values to avoid rounding errors.
ใช้เมื่อใด: Multi-step calculations where premature rounding loses the final accuracy mark.
ขั้นตอน
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
ข้อควรระวังในการสอบ: 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)
วัตถุประสงค์: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
ใช้เมื่อใด: As a check only, after solving by hand.
ขั้นตอน
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
ข้อควรระวังในการสอบ: 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.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 1Challenges of an urbanising world
Forgetting to round calculation answers to exactly one decimal place as explicitly requested in the prompt.
วิธีหลีกเลี่ยง: Circle the rounding instruction on your exam paper. Write the full unrounded calculation out first, then write your final rounded answer to 1 decimal place with units.
2mediumคะแนนที่เกี่ยวข้อง: 4Hazardous Earth
Confusing the natural physical causes of climate change with human-induced enhanced greenhouse effects.
วิธีหลีกเลี่ยง: Clearly distinguish astronomical factors (e.g. Milankovitch orbital cycles) and geological factors (volcanic ash/dust blocking solar radiation) from modern human activities (fossil fuels, deforestation).
3mediumคะแนนที่เกี่ยวข้อง: 2Geographical investigations - Investigating coastal change and conflict
Failing to explicitly link fieldwork data limitations to specific data collection timings (e.g. Saturday morning snapshots).
วิธีหลีกเลี่ยง: State how the specific day or time of your data collection created a biased, non-representative sample of the environmental or demographic reality.
4highคะแนนที่เกี่ยวข้อง: 4Challenges of an urbanising world
Providing generic answers to megacity and case-study questions without referencing specific named locations or local statistics.
วิธีหลีกเลี่ยง: Always use named case-study locations (e.g., Dharavi in Mumbai, Makoko in Lagos) and specific data points rather than general descriptions of urban poverty.
5highคะแนนที่เกี่ยวข้อง: 3Consuming energy resources
Failing to structure extended responses (8- and 12-mark questions) with a clear balance of positive and negative points prior to making a judgment.
วิธีหลีกเลี่ยง: Plan a two-sided argument before writing. State your main argument in paragraph one, contrast it in paragraph two, and deliver a definitive judgment in your conclusion.
6mediumคะแนนที่เกี่ยวข้อง: 1The UK’s evolving human landscape
Failing to show step-by-step mathematical working out on percentage calculations, losing partial method marks if the final answer is wrong.
วิธีหลีกเลี่ยง: Always write down the full formula: ((New - Old) / Old) x 100, show your substitution steps, and then write the final answer clearly.
7mediumคะแนนที่เกี่ยวข้อง: 4Geographical investigations - Investigating coastal change and conflict
Evaluating the strengths and weaknesses of a fieldwork plan without direct reference back to the actual enquiry question itself.
วิธีหลีกเลี่ยง: Constantly tie every strength or weakness back to how it affects the reliability, validity, and overall accuracy of the data needed to answer that specific enquiry.
8mediumคะแนนที่เกี่ยวข้อง: 3Consuming energy resources
Struggling to differentiate between physical causes of economic decline (such as volcanic eruptions/storms) and human/global economic factors on Paper 3.
วิธีหลีกเลี่ยง: Categorize your factors strictly. Physical causes relate to natural hazards and climate, while human factors involve debt, international trade, and political relationships.
9highคะแนนที่เกี่ยวข้อง: 2Challenges of an urbanising world
Lacking numerical evidence when describing relationships in scatter graphs or correlations.
วิธีหลีกเลี่ยง: Always quote specific data coordinates (e.g., x-axis values and y-axis percentages) for at least two points on the graph to prove the correlation.
10highคะแนนที่เกี่ยวข้อง: 6Consuming energy resources
Failing to make a clear, justified choice between Option 1, 2, and 3 in the final Paper 3 essay, ending with an ambiguous, non-committal conclusion.
วิธีหลีกเลี่ยง: State your chosen option clearly in the opening sentence. Systematically justify it using resource evidence and explicitly reject the remaining options.
