Describing multiple research studies or techniques in Section A SAQs, which wastes precious exam time.

Present and detail exactly one high-quality, relevant study. Examiners will only grade the first study described.

Confusing enculturation (learning native cultural schemas) with acculturation (cultural change from foreign contact).

Explicitly define enculturation as internalizing one's primary native culture and acculturation as adjusting to a new culture.

Providing a one-sided evaluation (strengths only or limitations only) in ERQs.

Ensure every evaluation essay presents a balanced review of both strengths and limitations to avoid a 3-mark cap on Criterion D.

Treating brain-imaging techniques (like MRI and fMRI) as research methods.

Classify fMRI/MRI as technology tools utilized within a research method like an experiment or case study.

Writing sequential descriptive essays for 'Contrast' questions in Paper 2 rather than directly comparing factors throughout.

Structure contrast essays comparatively from the start, highlighting explicit similarities and differences throughout the response.

Failing to explicitly link animal research findings back to human neurobiology and behavior.

When utilizing animal models, actively write a conceptual bridge detailing the specific evolutionary or physiological links to human behavior.

计算器规定

A graphic display calculator (GDC) from the IB-approved list is required for most Mathematics and Sciences papers and must be set to examination mode. Note that some papers do not permit a calculator (for example Mathematics Paper 1 and the multiple-choice Sciences Paper 1).

AO1: Knowledge and comprehension
AO2: Application and analysis
AO3: Synthesis and evaluation

根据历届试题与评分标准整理（2023–2025）。

计算器程序

Graph: zeros, intersections & turning points

Graphical calculator / GDC (exam mode)

用途: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.

使用时机: Checking solutions, sketching, or solving where an analytic method is hard.

步骤

Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.

考试提示: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

Numerical equation solver

Graphical calculator / GDC (exam mode)

用途: Solve an equation or find a variable numerically when an algebraic route is long or implicit.

使用时机: Iterative or implicit equations, or to confirm an algebraic solution.

步骤

Use the equation/zero solver, entering the equation and a sensible starting estimate.

考试提示: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

Numerical integration & differentiation

Graphical calculator / GDC (exam mode)

用途: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.

使用时机: Checking calculus answers, or where only a numerical value is needed.

步骤

Use the GDC's numeric integral / derivative function with the limits or the point.

考试提示: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.

Statistics & probability distributions

Graphical calculator / GDC (exam mode)

用途: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.

使用时机: Statistics questions and hypothesis tests.

步骤

Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).

考试提示: Use a GDC from the IB-approved list in examination mode. Some papers do not permit a calculator. Always show your reasoning.
