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: Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures (38%)
AO2: AO2: Apply knowledge and understanding of scientific ideas, processes, techniques and procedures (42%)
AO3: AO3: Analyse, interpret and evaluate scientific information, ideas and evidence (20%)
วัตถุประสงค์: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
ใช้เมื่อใด: Checking solutions, sketching, or solving where an analytic method is hard.
ขั้นตอน
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
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.
Numerical equation solver
Graphical calculator / GDC (exam mode)
วัตถุประสงค์: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
ใช้เมื่อใด: Iterative or implicit equations, or to confirm an algebraic solution.
ขั้นตอน
Use the equation/zero solver, entering the equation and a sensible starting estimate.
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.
Numerical integration & differentiation
Graphical calculator / GDC (exam mode)
วัตถุประสงค์: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
ใช้เมื่อใด: Checking calculus answers, or where only a numerical value is needed.
ขั้นตอน
Use the GDC's numeric integral / derivative function with the limits or the point.
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 & probability distributions
Graphical calculator / GDC (exam mode)
วัตถุประสงค์: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
ใช้เมื่อใด: Statistics questions and hypothesis tests.
ขั้นตอน
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
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: 2Cells and microscopy
Describing active transport as the 'production of energy' or saying it 'creates energy'.
วิธีหลีกเลี่ยง: Use correct terminology: state that active transport 'requires ATP' or 'uses energy from respiration'.
2highคะแนนที่เกี่ยวข้อง: 2Cells and microscopy
Failing to convert initial physical measurement units (e.g., mm to micrometers) before dividing by the magnification factor.
วิธีหลีกเลี่ยง: Always measure your scale bar in mm, multiply by 1,000 to convert to micrometers (\(\mu\text{m}\)), and then divide by the magnification.
3mediumคะแนนที่เกี่ยวข้อง: 1Gas exchange in mammals and plants
Using imprecise terminology like 'hairs' instead of 'cilia' when describing respiratory mucosal defenses.
วิธีหลีกเลี่ยง: Use the word 'cilia' explicitly and explain that they 'waft' or 'move' mucus and pathogens up the airways.
4mediumคะแนนที่เกี่ยวข้อง: 1Cells and microscopy
Writing generic descriptions of 'transport proteins' rather than distinguishing channel and carrier proteins.
วิธีหลีกเลี่ยง: Be specific about whether you are discussing a 'channel protein' or a 'carrier protein' and explain their exact role in active transport or facilitated diffusion.
5mediumคะแนนที่เกี่ยวข้อง: 2The developing cell: cell division and cell differentiation
Confusing G1 and G2 checkpoints, specifically thinking DNA replication checks occur at G1.
วิธีหลีกเลี่ยง: Remember that G1 is pre-replication (checking cell size and DNA damage), while G2 is post-replication (checking that DNA replicated correctly in the S phase).
6highคะแนนที่เกี่ยวข้อง: 1The developing individual: meiosis, growth and development
Failing to round calculated answers to the requested number of significant figures (such as 2 significant figures).
วิธีหลีกเลี่ยง: Check the prompt for rounding instructions before writing down your final answer, e.g., rounding 5.75g to 5.8g.
7highคะแนนที่เกี่ยวข้อง: 2Cells and microscopy
Including sketching or shading on low-power plan tissue drawings.
วิธีหลีกเลี่ยง: Draw single, continuous, clear lines using a sharp HB pencil. Do not draw individual cells or use shading of any kind.
8mediumคะแนนที่เกี่ยวข้อง: 1The heart and monitoring heart function
Neglecting to mention 'walls' or 'cardiac muscle' explicitly when describing ventricular or atrial contraction.
วิธีหลีกเลี่ยง: Always state that the 'ventricular wall' or 'cardiac muscle' contracts, rather than just saying 'the ventricle contracts' to ensure full marks.
