電卓の規定
A silent scientific calculator may be used on papers where calculators are permitted (some papers are non-calculator). It must not be graphical or programmable and must hold no stored information.
AO1: Knowledge with understanding (50%)
AO2: Handling information and problem-solving (30%)
AO3: Experimental skills and investigations (20%)

電卓プログラム
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
目的: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使う場面: Solving or sketching a function when you want to find where its graph crosses or turns.
手順
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
試験での注意: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
目的: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使う場面: Any data-handling, statistics, or required-practical analysis question.
手順
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
試験での注意: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
目的: Keep full-precision intermediate values to avoid rounding errors.
使う場面: Multi-step calculations where premature rounding loses the final accuracy mark.
手順
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
試験での注意: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
目的: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使う場面: As a check only, after solving by hand.
手順
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
試験での注意: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
よくあるミス
1high影響する配点: 2Enzymes
Stating that high temperatures or extreme pH levels 'kill' enzymes.
回避方法: State that high temperatures or extreme pH levels 'denature' enzymes or affect their 'active site shape'.
2high影響する配点: 1Transpiration
Describing the movement of water during transpiration as 'water' diffusing through air spaces.
回避方法: Specify that 'water vapour' (not liquid water) diffuses from the surface of mesophyll cells through the air spaces and out of the stomata.
3high影響する配点: 1Homeostasis
Confusing the hormone 'glucagon' with the storage carbohydrate 'glycogen' during homeostasis explanations.
回避方法: Remember the rule: when glucose is GONE, you need glucaGON (the hormone). Glycogen is the polysaccharide stored in the liver.
4high影響する配点: 2Size of specimens
Applying sketching lines, stippling, or shading to biological drawings in Paper 5 & 6.
回避方法: Draw single, clean, continuous outlines with a sharp HB pencil. Do not shade or stipple any part of the specimen.
5medium影響する配点: 1Size of specimens
Writing raw units (like 'mm' or '°C') directly inside the data fields of a results table.
回避方法: Keep units strictly within the column and row headers of your results table (e.g., 'Temperature / °C' or 'Time / s'), leaving table body cells as raw numbers.
6medium影響する配点: 1Size of specimens
Failing to include a negative sign when calculating percentage decreases.
回避方法: Always insert a negative sign (-) in front of your final value if calculating a percentage decrease (e.g., -61.8%), or clearly state the term 'percentage decrease'.
7high影響する配点: 3Size of specimens
Multiplying by 1000 instead of dividing by 1000 when converting micrometer measurements to millimeters for magnification equations.
回避方法: To convert micrometers to millimeters, divide the value by 1000. Ensure both image size and actual size are converted to identical units before division.
8high影響する配点: 2Pollution
Omitting the role of bacteria and decomposers when describing eutrophication.
回避方法: State that bacteria feed on the dead producers and multiply rapidly, consuming dissolved oxygen through aerobic respiration, which suffocates the fish.
9medium影響する配点: 2Heart
Misidentifying the anatomical left and right sides of the heart on cardiorespiratory diagrams.
回避方法: Remember that anatomical diagrams are drawn from the perspective of the patient facing you. The right ventricle is on the left side of the paper, and the left ventricle is on the right.
10medium影響する配点: 1Aerobic respiration
Writing 'air' instead of 'oxygen' when describing the requirements of aerobic respiration.
回避方法: Always use the specific gas name 'oxygen' rather than the general term 'air' in respiration equations and descriptions.
