ข้อกำหนดเครื่องคิดเลข
A scientific or graphical calculator is permitted. Graphical calculators must be in exam mode with all stored programs and data cleared before the exam; the calculator must not be able to retrieve stored text or formulae.
AO1: AO1: 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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
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, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 1Respiration
Stating that 'energy is produced' or 'created' during cellular respiration or biochemical reactions.
วิธีหลีกเลี่ยง: Always use precise scientific language: state that energy is 'released' or that 'ATP is produced'.
2highคะแนนที่เกี่ยวข้อง: 3Allele frequencies in populations (Populations and genes)
Equating the frequency of the dominant phenotype directly with the p or p^2 terms in the Hardy-Weinberg equation, ignoring the 2pq heterozygous term.
วิธีหลีกเลี่ยง: Always start by identifying the homozygous recessive phenotype frequency (q^2), compute q by taking its square root, then find p (1 - q), and use these to compute heterozygous frequency (2pq).
3mediumคะแนนที่เกี่ยวข้อง: 2Genetic diversity may arise by meiosis
Drawing haploid daughter cells at the end of meiosis (e.g. stage D) with two chromatids instead of single-chromatid structures.
วิธีหลีกเลี่ยง: Ensure that chromosomes drawn in final haploid gametes are represented as single lines (one chromatid per chromosome) to show meiosis II is complete.
4mediumคะแนนที่เกี่ยวข้อง: 2Respiration
Failing to divide the given internal diameter of a capillary tube by 2 before calculating the volume using the formula pi * r^2 * h.
วิธีหลีกเลี่ยง: Always divide the diameter by 2 first to get the radius, then use the radius in the cylinder volume formula.
5highคะแนนที่เกี่ยวข้อง: 2Living organisms vary
Declaring that two experimental groups are significantly different or not different without explicitly mentioning whether standard deviation or standard error bars overlap.
วิธีหลีกเลี่ยง: Specifically state whether the standard deviation or standard error bars overlap or do not overlap, and link this clearly to whether the difference is statistically significant.
6mediumคะแนนที่เกี่ยวข้อง: 1Biological molecules
Describing the product of joining two amino acids as a 'polypeptide' rather than a 'dipeptide'.
วิธีหลีกเลี่ยง: Use the specific term 'dipeptide' when referring to the combination of exactly two amino acids. A polypeptide refers to a longer chain of amino acids.
7highคะแนนที่เกี่ยวข้อง: 2Cells and cell structure
Failing to convert units (such as millimetres to micrometers) before carrying out magnification calculations.
วิธีหลีกเลี่ยง: Convert all linear measurements to the requested units (e.g., multiply millimetres by 1,000 to convert to micrometers) before using the magnification formula.
8mediumคะแนนที่เกี่ยวข้อง: 1Transport into and out of cells
Forgetting to include the negative sign (-) in percentage change calculations when there is a decrease in value.
วิธีหลีกเลี่ยง: Always write a negative sign or state clearly that it is a decrease when the final value is less than the initial value.
9highคะแนนที่เกี่ยวข้อง: 1Allele frequencies in populations (Populations and genes)
Writing final mathematical answers as long decimals instead of rounding to the requested number of significant figures or standard form.
วิธีหลีกเลี่ยง: Read the prompt carefully for formatting requirements (e.g. standard form, 2 significant figures, or 1 decimal place) and apply this to your final answer.
