ข้อกำหนดเครื่องคิดเลข
A silent scientific calculator is required where the syllabus permits one. It must NOT be graphical, programmable, or capable of symbolic algebra (CAS), and it must contain no stored programs or notes.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
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 the calculator must be silent, non-graphical, non-programmable and free of stored content; always show the working the mark scheme requires.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 4Classification of goods and services
Classifying state-provided private/merit goods (like free municipal healthcare or state schools) as public goods.
วิธีหลีกเลี่ยง: Clearly identify that municipal healthcare and state schools are rival and excludable, which classifies them as private/merit goods provided free of charge, not true public goods (which must be non-rival and non-excludable).
2highคะแนนที่เกี่ยวข้อง: 2Factors of production
Conflating overall industrial 'production' with factor 'productivity'.
วิธีหลีกเลี่ยง: Define production as total output volume (e.g. total tons of agricultural output) and productivity as output per unit of factor input (e.g. output per worker hour).
Shifting the entire PPC curve to the left when illustrating short-run domestic unemployment.
วิธีหลีกเลี่ยง: Keep the PPC stationary and draw a point moving from the curve to the interior space, representing the under-utilization of existing resources.
4mediumคะแนนที่เกี่ยวข้อง: 2Aggregate Demand and Aggregate Supply analysis
Mislabeling aggregate demand and supply (AD/AS) diagrams with microeconomic axes labels (Price and Quantity).
วิธีหลีกเลี่ยง: Always label macroeconomic diagram axes as 'Price Level' (vertical) and 'Real GDP' or 'Real Output' (horizontal).
5highคะแนนที่เกี่ยวข้อง: 4Effectiveness of policy options to meet all macroeconomic objectives
Providing one-sided analysis in Part (b) essays, which caps the maximum score for AO3 Evaluation.
วิธีหลีกเลี่ยง: Develop a balanced two-sided perspective highlighting both benefits and limitations of a policy, ending with a highly context-specific, justified final conclusion.
6mediumคะแนนที่เกี่ยวข้อง: 6Current account of the balance of payments
Conflating 'Terms of Trade' (relative price index ratio) with 'Balance of Trade' (monetary net trade value).
วิธีหลีกเลี่ยง: Define Terms of Trade mathematically as (Index of Export Prices / Index of Import Prices) * 100, distinguishing it completely from net current account transactions.
