ข้อกำหนดเครื่องคิดเลข
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.
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: 3Changing cities
Failing to explicitly name and locate a real-world city (such as Bristol, Mumbai, or Rio de Janeiro) in the Changing Cities essay responses.
วิธีหลีกเลี่ยง: Always mention your studied city case studies by name on high-tariff essays, integrating at least three specific local facts, policies, or demographic statistics to lift your response into the higher mark bands.
2highคะแนนที่เกี่ยวข้อง: 2Geographical investigations − UK challenges
Using vague evaluation adjectives like 'cheaper', 'easier', or 'quicker' on Paper 3 without structural or geographic elaboration.
วิธีหลีกเลี่ยง: Explain the physical, economic, or logistical mechanism behind the cost/benefit. For example, explain how using local soft-engineering materials like marram grass planting reduces high capital import costs.
3highคะแนนที่เกี่ยวข้อง: 2Weather hazards and climate change
Failing to extract specific quantitative values from graphs to support analytical statements (e.g., Sahel rainfall variations or Holderness erosion rates).
วิธีหลีกเลี่ยง: Always practice extracting minimum, maximum, or change values directly from the figures provided. Cite these exact numbers and years directly in your written response.
4mediumคะแนนที่เกี่ยวข้อง: 4Global development
Losing SPaG marks on high-tariff essays due to spelling errors in complex geographical terms.
วิธีหลีกเลี่ยง: Create a dedicated spelling glossary during your revision for high-risk terms like 'desalination', 'hydroelectric', 'eutrophication', and 're-urbanisation' to protect your 4 SPaG marks.
5mediumคะแนนที่เกี่ยวข้อง: 2Global development
Providing circular or mirrored explanations for developmental indicators, such as stating GNI causes development because the country becomes more developed.
วิธีหลีกเลี่ยง: Provide the precise sequential steps of the mechanism. E.g., explain that higher GNI increases government tax yields, which are reinvested into healthcare infrastructure, lowering infant mortality.
Omitting units (such as 'mm', '%', or 'Mha') in mathematical calculation questions.
วิธีหลีกเลี่ยง: Always scan the final answer line to see if the unit is pre-printed. If it is not, write down the unit immediately alongside your final calculated number.
7mediumคะแนนที่เกี่ยวข้อง: 1Ecosystems, biodiversity and management
Misclassifying 'wood' as an abiotic resource or 'soil' as a biotic resource due to confusion between biological and physical ecosystem components.
วิธีหลีกเลี่ยง: Remember that 'biotic' represents living or organic components (e.g., plants, animals, bacteria) while 'abiotic' represents non-living, physical components (e.g., soil, rock, water, sunlight).
8lowคะแนนที่เกี่ยวข้อง: 2Coastal landscapes and processes
Believing that constructive waves erode beaches, rather than building them up.
วิธีหลีกเลี่ยง: Understand that constructive waves have a strong swash and a weak backwash, which deposits sediment on the beach, whereas destructive waves have a strong backwash that erodes the beach.
9highคะแนนที่เกี่ยวข้อง: 2Geographical investigations – Investigating human environments
Assuming random sampling in fieldwork guarantees a perfectly representative sample of your study area.
วิธีหลีกเลี่ยง: Recognize that random sampling can lead to geographic clustering, leave large areas unsampled, or direct students to unsafe and inaccessible locations.
