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.
AO1: AO1: Use and apply standard techniques (50%)
AO2: AO2: Reason, interpret and communicate mathematically (25%)
AO3: AO3: Solve problems within mathematics and in other contexts (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 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: 2Solving equations and inequalities (Algebra)
Squaring negative numbers incorrectly by typing or writing -4^2 = -16 instead of (-4)^2 = 16.
วิธีหลีกเลี่ยง: Always place negative numbers inside brackets when squaring them: (-4) x (-4) = 16. On calculators, type '(-4)^2'.
2mediumคะแนนที่เกี่ยวข้อง: 1Measures and accuracy (Number)
Failing to round up in real-life discrete contexts, such as calculating 7.2 teachers needed for a trip and giving 7 as the answer.
วิธีหลีกเลี่ยง: Identify real-world constraints: 7 teachers would leave some students unsupervised. Always round up to the next integer (8) in capacity or safety contexts.
3highคะแนนที่เกี่ยวข้อง: 3Statistics (Statistics)
Confusing 360 degrees with 100 percent when calculating angles or drawing sectors for pie charts.
วิธีหลีกเลี่ยง: Always use 360 degrees as the total denominator for circle calculations. Divide the category frequency by the total population, then multiply by 360.
4highคะแนนที่เกี่ยวข้อง: 1Measures and accuracy (Number)
Premature rounding of intermediate decimals, leading to a slight discrepancy in the final digit of multi-step calculator problems.
วิธีหลีกเลี่ยง: Keep intermediate values written in exact form (like fractions or multiples of pi) or store them in your calculator memory, rounding only the very final value.
5mediumคะแนนที่เกี่ยวข้อง: 1Structure and calculation (Number)
Writing invalid monetary notations such as £4.2 instead of standard £4.20.
วิธีหลีกเลี่ยง: Always express sterling currency to exactly two decimal places when pence are involved. Write £4.20 to meet examiner standards.
6mediumคะแนนที่เกี่ยวข้อง: 2Measures and accuracy (Number)
Attempting to perform decimals estimation by computing the exact product first and then rounding, which wastes valuable time and increases arithmetic risk.
วิธีหลีกเลี่ยง: Round each number in the question to 1 significant figure first (e.g., 31 becomes 30, and 18 becomes 20), then perform the simple multiplication (30 x 20 = 600).
