Electrochemistry, Chemical Kinetics, Coordination Compounds, Organic Chemistry, and Biomolecules &#8211; these chemistry class 12 chapters have higher weightage; therefore, start from these. This helps you cover the high-mark areas early, and if you are out of time for other chemistry topics, your score is secured.<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><strong>Use the NCERT Book as Your Bible<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p>When it comes to achieving the dream of scoring high in Chemistry, never overlook the power of chemistry class 12 NCERT solutions Part I and II. Examples, in-text questions, and back exercises &#8211; you will find most of the questions from these sections. The key is to read chemistry book class 12 for the reactions, definitions, exceptions, and tables thoroughly. The footnotes and diagrams are also important.<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><strong>Divide Study Time Chapter-Wise<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Studying any topic randomly? Allocate your time according to the marks distribution. Give 4 days to high-weightage topics, 2 days to medium-weightage topics, and 1 day to low-weightage topics. The result? It will help you prevent studying small chapters again and again while giving less focus to important units. You can create a timetable for yourself and swear by it. Solving <\/span><a href=\"https:\/\/www.aakash.ac.in\/boards\/cbse-class-12-chemistry-sample-question-paper-solutions\"><b>chemistry sample paper class 12<\/b><\/a><span style=\"font-weight: 400;\"> also helps<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><strong>Practice Numericals &amp; Conversions Daily<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Yes! Physical Chemistry has a lot of calculations but it offers you chances to score high. Molarity, Nernst equation, rate constants, and electrolysis &#8211; all these topics demand practice. The suggestion? Do 20\u201330 numericals daily. The more practice, the more accurate and faster the results during the exam. Another suggestion? Have a separate notebook for formulas.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">\n<h3><strong>Revise Organic &amp; Inorganic With Short Notes<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p><b>Organic chemistry topics <\/b><span style=\"font-weight: 400;\">like reactions and Inorganic trends &#8211; both require strong memorisation, and a long reading method does not help. You can create flashcards, reaction charts, write reactions, and learn color changes, ores, and exceptions.
