Last Updated - April 09, 2017

JEE Main Exam is conducted by CBSE all over India. This exam is conducted to get admission in Under Graduate (UG) Engineering Programmes at various top ranking institutes. JEE Main Exam has mainly two papers. Paper 1 is for the aspirants who wants to go in engineering programmes. Paper 2 is for the aspirants who want admission in B.Arch. or B.Plann Degree courses. If you are confused between the courses, then you may answer both the Papers. JEE Main 2016 will be conducted on 3rd April, 2016 and this will be offline exam for both the papers. On 9th and 10th April, 2016 the only JEE Main 2016 Paper 1 Online Mode will be held. Both of these papers are held in 3 hours duration. Paper 1 has Physics, Chemistry and Mathematics as the subjects which consists of objective types questions.

JEE Main Exam has a total number of 30 questions in chemistry section. Each question has 4 different multiple choices. Every question in this section carries 4 marks. The correct choice marked answer will get you achieve 4 marks and the wrong choice marked answer will deduct -1.
