Final Words
By using the previous year’s trend of topic-wise weightage for JEE Main 2026, candidates can prepare using a smarter plan and in a more focused way. Candidates should concentrate on high-weightage topics that are asked repeatedly in the exam, instead of giving equal time to every chapter.
Topics like Modern Physics and Electricity deserve special attention in Physics. Chemistry preparation should cover important concepts from Physical, Organic, and Inorganic Chemistry, strongly based on the NCERT. In Mathematics, Algebra and Calculus remain the most important and high-scoring areas. With the right planning and by studying according to past trends, students can score better in JEE Main 2026 and increase their chances of getting into top engineering colleges.
