计算器规定
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 and understanding of scientific ideas, techniques and procedures (40%)
AO2: AO2: Apply knowledge and understanding of scientific ideas, enquiry, techniques and procedures (40%)
AO3: AO3: Analyse information and ideas to interpret and evaluate, make judgements and draw conclusions, and develop and improve experimental procedures (20%)

计算器程序
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
用途: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使用时机: Solving or sketching a function when you want to find where its graph crosses or turns.
步骤
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
考试提示: 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)
用途: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使用时机: Any data-handling, statistics, or required-practical analysis question.
步骤
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
考试提示: 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)
用途: Keep full-precision intermediate values to avoid rounding errors.
使用时机: Multi-step calculations where premature rounding loses the final accuracy mark.
步骤
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
考试提示: 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)
用途: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使用时机: As a check only, after solving by hand.
步骤
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
考试提示: 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.
常见错误
1high涉及分数: 2Key concepts in biology (Paper 1)
Stating that enzymes are 'killed' at high temperatures or extreme pH.
如何避免: Always write that enzymes are 'denatured' and explain that the active site has changed shape, preventing the substrate from fitting/binding.
2high涉及分数: 1Cells and control (Paper 1)
Confusing corrective lens types for myopia, recommending a convex/converging lens.
如何避免: Remember that a concave (diverging) lens is required to correct short-sightedness (myopia), while a convex lens is used for long-sightedness.
3high涉及分数: 1Key concepts in biology (Paper 2)
Failing to explicitly round calculated numbers to the requested decimal place (e.g., leaving 7.28 instead of 7.3).
如何避免: Always carefully read the final sentence of calculation questions and apply the requested rounding (e.g., 'to 1 decimal place' or 'to the nearest whole number').
4medium涉及分数: 2Cells and control (Paper 1)
Confusing iris muscles with ciliary muscles in explanations of pupil size and accommodation.
如何避免: The iris muscles (radial and circular) control the pupil's response to light levels, whereas the ciliary muscles (and suspensory ligaments) alter lens shape to focus on objects at different distances.
5high涉及分数: 2Key concepts in biology (Paper 1)
Omitting key quantitative controls in experiment 'devise' or 'plan' prompts.
如何避免: Always specify exact variables that must be controlled, such as using the same volumes, same concentrations, or same starting temperatures of solutions.
6medium涉及分数: 2Key concepts in biology (Paper 2)
Stating that root hair cells contain chloroplasts.
如何避免: Explain that root hair cells grow underground without light; because they cannot photosynthesise, they lack chloroplasts completely.
7medium涉及分数: 1Cells and control (Paper 1)
Stating that human somatic cells have 23 chromosomes in mitosis.
如何避免: Remember that human body cells contain 46 chromosomes (23 pairs); only gametes produced during meiosis contain 23 chromosomes.
8high涉及分数: 1Key concepts in biology (Paper 1)
Omitting the heating/boiling step when describing Benedict's test for reducing sugars.
如何避免: Ensure you state that the sample mixed with Benedict's solution must be heated or placed in a boiling water bath for the reaction to occur.
