In many IGCSE items, \u201cshow that\u201d expects a structured chain of algebraic steps or theorem-based reasoning that reaches the given result exactly.A strong rule is: If your solution would still work for all valid values (not just one example), then it is proof-like enough for the marking scheme.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What is the difference between &amp;quot;solve&amp;quot; and &amp;quot;simplify&amp;quot;?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p><strong>Solve<\/strong>\u00a0means find the value(s) of the unknown(s) that satisfy an equation, inequality, or system, and state the solution clearly. <strong>Simplify<\/strong>\u00a0means rewrite an expression or equation into an equivalent, cleaner form without changing what it represents.If there is no equals sign, you usually cannot \u201csolve\u201d it; you simplify it.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>How many marks are lost by misinterpreting command words?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>It depends on how many multi-mark questions are affected, but misinterpreting command words commonly costs method marks even when the final answer is correct. A single \u201cshow that\u201d done as a numerical check can lose most or all reasoning marks, and a \u201cdraw\u201d treated like a sketch can lose accuracy marks.In practice, the cumulative loss can be large enough to shift a boundary outcome, especially for students clustered around grade thresholds.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What does &amp;quot;hence&amp;quot; imply in an IGCSE Maths question?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>\u201cHence\u201d means you should use the result from the previous part to complete the next part with minimal new work. The marking scheme typically expects you to leverage the earlier expression, value, or relationship directly rather than starting again from scratch.If you ignore the \u201chence\u201d link, you may still get the answer, but you often waste time and increase error risk.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Do I need to draw to scale when the word &amp;quot;sketch&amp;quot; is used?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>No, a sketch does not require scale accuracy unless the question explicitly states otherwise. You should focus on key features such as intercepts, turning points, asymptotes, and overall shape.If you spend time making it perfect, you are trading marks for aesthetics, which the marking scheme does not reward.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Where can I find a full list of IGCSE command words?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p>You can find command-word lists in Cambridge syllabus documents and examiner-style guidance for the relevant qualification, and they also appear implicitly across past papers and mark schemes.Based on our years of practical tutoring at Times Edu, the most effective \u201clist\u201d is a personalised checklist built from your past-paper errors, because it targets the command words you misread under pressure.<\/p>\n<p>If you want, Times Edu can audit your recent papers, map your errors to command-word categories, and build a 2\u20134 week correction plan aligned to assessment objectives and the marking scheme.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<h4>Conclusion<\/h4>\n<p>If you are aiming for top grades, treat IGCSE maths command words as a scoring framework, not vocabulary.
