ข้อกำหนดเครื่องคิดเลข
A scientific or graphical calculator is permitted. Graphical calculators must be in exam mode with all stored programs and data cleared before the exam; the calculator must not be able to retrieve stored text or formulae.
AO1: AO1: Knowledge of locations, places, environments, processes, and concepts. (25%)
AO2: AO2: Understanding of geographical concepts and interrelationships. (25%)
AO3: AO3: Apply understanding to interpret, analyse, and evaluate geographical information. (25%)
AO4: AO4: Use a range of skills and techniques to collect, represent, and analyze data. (25%)
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 3Geographical Enquiry (Section B)
Confusing data presentation methods (like bar charts, scatter graphs) with data collection methods (like questionnaires) in Section B.
วิธีหลีกเลี่ยง: Group your fieldwork concepts clearly: collection is how you obtained the raw measurements, while presentation is how you visually represented those figures on paper.
Lifting quantitative data directly from the Resource Booklet figures without providing any geographical context, process, or consequence.
วิธีหลีกเลี่ยง: Use the 'So What?' technique: quote the exact statistic from the figure, and immediately explain the underlying cause or consequence of that trend.
3mediumคะแนนที่เกี่ยวข้อง: 2Fieldwork Title and Locations
Writing generic, non-specific locations for fieldwork (e.g. 'the local river') instead of citing specific geographical locations, site numbers, and project titles.
วิธีหลีกเลี่ยง: Memorize and write out your exact, formal fieldwork title with named location, county, or country to establish geographical validity immediately.
4highคะแนนที่เกี่ยวข้อง: 4Extended Writing Essays
Failing to write a balanced, two-sided argument and a justified final conclusion on high-tariff (8 and 12-mark) questions.
วิธีหลีกเลี่ยง: Structure your long-form answers to present both viewpoints (e.g., physical vs. human factors) and always dedicate your last paragraph to a clear, summary judgment.
5mediumคะแนนที่เกี่ยวข้อง: 2River Environments
Believing that river velocity always decreases downstream due to gentler gradients.
วิธีหลีกเลี่ยง: Remember that average river velocity actually increases downstream because channels become smoother and more efficient, reducing friction.
6mediumคะแนนที่เกี่ยวข้อง: 1Quantitative and Statistical Skills
Omitting mathematical working or units on simple calculations (such as percentage change or range questions).
วิธีหลีกเลี่ยง: Always write out your formula, show step-by-step substitution, and check that the correct units (e.g., %, m³/s, km³) are clearly appended to the final answer.
