JEE Main has two papers, Paper-1 and Paper-2. Candidates may opt for either or both of them. Both papers contain multiple choice questions. Paper 1 is for admission to B.E./B.Tech courses and is conducted in both online and offline modes. Paper-2 is for admission in B.Arch and B.Planning courses and is conducted offline only.
JEE Mains, unlike JEE Advanced, has a fixed exam structure. Paper-1 is of three hours duration and consists of thirty multiple-choice (single-correct) questions in each of the three subjects (physics, chemistry and maths). There is negative marking for incorrect answers. 4 marks are awarded for correct answers and 1 mark is deducted for incorrect answers. From 2013 to 2016, the marks obtained in the class XII school board examination used to be accorded a 40% weightage in deciding the JEE Mains all India ranks.
