If you see newtons, you are dealing with a force.<strong>Use the relationship W = mg only when g is relevant. <\/strong>Many students wrongly apply g in contexts that only ask for mass.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>Do examiners give marks for working even if the answer is wrong?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p><strong>Yes, method marks are commonly available if your process is correct. <\/strong>That is why showing formula, substitution, and units is a scoring strategy.<strong>If you skip working, you remove the examiner\u2019s ability to award partial credit. <\/strong>This is one of the most avoidable IGCSE physics mistakes in exams.<\/p>\n<\/div>\n<\/div>\n<div class=\"thong-tin-dai\">\n<p class=\"tit-dai\"><strong>What are the common errors in reading scales and instruments?<\/strong><\/p>\n<div class=\"chi-tiet-thong-tin\">\n<p><strong>The most common issue is parallax and poor scale interpretation. <\/strong>Students read from an angle or mis-handle minor divisions.<strong>Always state the precision of the instrument where required. <\/strong>If a ruler measures to the nearest mm, your recorded value should reflect that resolution.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><strong>Conclusion<\/strong><\/p>\n<p>Most students do not need \u201cmore content.\u201d They need a targeted correction system that eliminates repeated IGCSE physics mistakes.<\/p>\n<p>Based on our years of practical tutoring at <a href=\"https:\/\/times.edu.vn\/en\/\">Times Edu<\/a>, our personalized support typically includes:<\/p>\n<ul>\n<li>A diagnostic of your top 10 recurring mistakes (units, significant figures, vector vs scalar, diagrams, algebra).<\/li>\n<li>A mark-scheme aligned training plan with weekly timed checkpoints.<\/li>\n<li>A subject and academic pathway consultation to support international applications.<\/li>\n<\/ul>\n<p>If you want a personalized IGCSE Physics study roadmap built around your current level, target grade, and intended university direction, Times Edu can structure a plan that improves both exam performance and the strength of your overall academic profile.<\/p>\n\n\n<div class=\"kk-star-ratings kksr-auto kksr-align-right kksr-valign-bottom\"\n    data-payload='{&quot;align&quot;:&quot;right&quot;,&quot;id&quot;:&quot;35112&quot;,&quot;slug&quot;:&quot;default&quot;,&quot;valign&quot;:&quot;bottom&quot;,&quot;ignore&quot;:&quot;&quot;,&quot;reference&quot;:&quot;auto&quot;,&quot;class&quot;:&quot;&quot;,&quot;count&quot;:&quot;1&quot;,&quot;legendonly&quot;:&quot;&quot;,&quot;readonly&quot;:&quot;&quot;,&quot;score&quot;:&quot;5&quot;,&quot;starsonly&quot;:&quot;&quot;,&quot;best&quot;:&quot;5&quot;,&quot;gap&quot;:&quot;5&quot;,&quot;greet&quot;:&quot;\u0110\u00e1nh gi\u00e1 b\u00e0i vi\u1ebft&quot;,&quot;legend&quot;:&quot;5\\\/5 - (1 vote)&quot;,&quot;size&quot;:&quot;24&quot;,&quot;title&quot;:&quot;IGCSE Physics 0625 Mistakes: 10 Errors That Cost A* in 2026&quot;,&quot;width&quot;:&quot;142.5&quot;,&quot;_legend&quot;:&quot;{score}\\\/{best} - ({count} {votes})&quot;,&quot;font_factor&quot;:&quot;1.25&quot;}'>\n            \n<div class=\"kksr-stars\">\n    \n<div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px;
