How to read this JEE Main Chemistry weightage table
These are counts of real questions, not predictions. A chapter high in this list has reliably produced marks across many years, so it earns revision time; a chapter with a high recent average but a lower total is one the exam has been leaning on lately. Click any chapter to see its year-by-year trend, its most-asked sub-topics, and free solved questions from it.
