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: Knowledge and understanding of scientific ideas, processes, techniques and procedures (35%)
AO2: Application of knowledge and understanding of scientific ideas, processes, techniques and procedures (35%)
AO3: Analyze, interpret and evaluate scientific information, ideas and evidence (20%)
AO4: Practical and experimental skills, including safety, uncertainty, and analysis of graphical data (10%)
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: 3Use of SI units and their prefixes
Failing to convert units to SI base units before entering them into equations (e.g. leaving frequencies in THz, currents in mA, or dimensions in mm).
วิธีหลีกเลี่ยง: Develop a habit of writing down the SI base equivalent in scientific notation (e.g., 462 THz = 4.62 x 10^14 Hz) before performing any calculation.
2mediumคะแนนที่เกี่ยวข้อง: 4Energy transfer by heating and doing work
Using the wrong specific heat capacity (SHC) value during state-change calculations, such as using liquid sodium's SHC when the substance is still solid.
วิธีหลีกเลี่ยง: Draw a quick temperature-time cooling curve and label the phases (solid, liquid, phase transition) to match the correct SHC values from the data table.
3highคะแนนที่เกี่ยวข้อง: 2Ideal gases
Using Celsius instead of Kelvin in ideal gas law (pV = nRT) calculations.
วิธีหลีกเลี่ยง: Always add 273.15 to any temperature value in Celsius before inserting it into ideal gas or kinetic theory equations.
4highคะแนนที่เกี่ยวข้อง: 2Limitation of physical measurements
Drawing gradient triangles on lines of best fit that are too small, failing to cover at least half of the line's length.
วิธีหลีกเลี่ยง: Explicitly draw a large right-angled triangle that spans more than half the length of your drawn line of best fit, and use the vertices' coordinates to calculate the gradient.
5mediumคะแนนที่เกี่ยวข้อง: 3Wind energy
Confusing radius and diameter when calculating the swept area of wind turbines (A = pi * r^2) or rates of thermal conduction.
วิธีหลีกเลี่ยง: Always check if the given dimension is a diameter; if so, divide it by 2 to get the radius before squaring it in the area formula.
Omitting the minus sign when describing negative gravitational potentials or negative charges in electric fields.
วิธีหลีกเลี่ยง: Remember that gravitational potential is always negative relative to infinity, and verify sign conventions for work done on or by the system.
7highคะแนนที่เกี่ยวข้อง: 2Radioactivity
Failing to subtract the background radiation count rate when describing or calculating the corrected count rate of a radioactive source.
วิธีหลีกเลี่ยง: Measure the background count rate over a long period first without the source, then subtract this value from the total count rate measured with the source.
