Chemistry for JEE Main

25 questions for 100 marks, in the same 20 + 5 format. Inorganic chemistry and much of organic chemistry follow NCERT closely, often testing a line or a table from the textbook. Physical chemistry needs numerical practice. Many questions take under a minute if you know them.
