JEE Main Exam Pattern & Important Questions

The NTA sets the JEE Main question papers. JEE Main consists of two papers. Students willing to enroll for should appear for Paper 1, and Paper 2 is for B.Arch and B.Plan. Paper 1 is conducted in 13 languages and is of 400 marks. Each subject: Physics, Chemistry, and Mathematics is divided into two sections and has 30 (20 MCQs + 10 Objective type) questions each. Students appear for only five objective questions out of 10 in Section B. The 3 hours written paper includes a negative marking system. Students gain four marks for each correct answer and lose one mark for every incorrect answer.
