Start by stating what the model captures well (strengths), then identify the <strong>modeling assumptions<\/strong>\u00a0and test their realism against the scenario, then explain how each limitation could change conclusions, and finish with a context-based decision about suitability.Use this scoring-ready framework:<\/p>\n<ul>\n<li>Define the model clearly (variables, distribution\/idealisation).<\/li>\n<li>List key assumptions explicitly (independence, linearity, smoothness, negligible mass, normality, constant parameters).<\/li>\n<li>For each assumption: State a limitation, justify why it may fail, and state impact on results.<\/li>\n<li>Conclude: \u201cSuitable for \u2026, but not suitable for \u2026 Unless \u2026\u201d.<\/li>\n<\/ul>\n<p>A common misconception is to write only negatives. Examiners reward balance because it shows <strong>critical thinking<\/strong>\u00a0rather than complaint.<\/p>\n<p>From our direct experience with international school curricula, the highest marks come from students who connect each limitation to a measurable effect like bias, skewed probabilities, sensitivity of an estimate, or unrealistic forces.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What is the difference between verify and show that?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>\u201cVerify\u201d means confirming a claim is correct, usually by substitution, checking conditions, or comparing both sides under given values.\u201cShow that\u201d means producing a logical chain of mathematics that leads to the stated result, often requiring algebraic manipulation or a short <strong>mathematical proof<\/strong>.<\/p>\n<p>If you only check one numerical example when asked to \u201cshow that,\u201d you usually lose generality marks.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>How are marks awarded for explanation questions?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>Explanation marks usually reward <strong>logic<\/strong>, correct linking statements, and correct interpretation of steps or results.They often sit inside AO2\/AO3, so you gain marks for stating assumptions, justifying a method choice, and giving <strong>contextual answers<\/strong>\u00a0that interpret what a parameter or result means. You lose marks when your explanation repeats calculations without adding reasons.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Do you need full sentences for math explanations?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>You need clarity, not literary style. Short, complete statements that justify a step are ideal, and bullet points are often acceptable if they are precise and logically ordered.Avoid fragments that remove the reason, such as \u201cbecause standard,\u201d since examiners cannot award justification marks for vague claims.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What does &amp;ldquo;evaluate&amp;rdquo; mean in a mathematical context?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>It means judge the quality or suitability of a method\/model using criteria, then reach a decision.A strong evaluate answer references <strong>validity<\/strong>, <strong>limitations of the model<\/strong>, sensitivity to <strong>modeling assumptions<\/strong>, and the practical meaning of errors. Your judgement must be tied to the question\u2019s context, not just abstract comments.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Common examples of reasoning questions in Core Pure?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>Typical Core Pure reasoning tasks include explaining why a method works, justifying a transformation, or giving a structured proof.Common examples are proving identities, justifying convergence\/divergence steps, explaining restrictions in complex numbers or matrices, and interpreting solutions to differential equations in context.<\/p>\n<p>These questions reward AO2 reasoning steps, so you should write the \u201cwhy\u201d behind key moves.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<h4>Conclusion<\/h4>\n<p>If you are aiming for top grades, \u201cmore questions\u201d is not the full solution. You need a repeatable method for <strong>command words<\/strong>, <strong>mathematical reasoning<\/strong>, and evaluation of models under AO2\/AO3.<\/p>\n<p>Based on our years of practical tutoring at <a href=\"https:\/\/times.edu.vn\/en\/\">Times Edu<\/a>, students who adopt these structures typically see faster, more stable gains than students who only increase volume.
