JEE Main 2018 Exam Analysis



JEE Main Analysis and Expected Cut-off-2018

The 2018 JEE Main paper pattern was similar to its 2017 counterpart; however, overall it was a relatively tougher exam in comparison with last year. The Mathematics paper in particular was rather lengthy but only slightly more challenging, with Physics and Chemistry proving to be a little more difficult in comparison with JEE Main 2017.

Each section of the paper was worth 120 marks, with the entire exam hence 360 marks.

Physics was relatively tougher than last year. There were 17 questions from the Class XII syllabus and 13 from Class XI. Some of the questions were straight out of standard textbooks, making them relatively easy to solve while others were quite tricky involving calculations and approximations as well. A good weightage was given to electrostatics, current electricity and mechanics

Chemistrytoo was relatively tougher than last year. There were 16 questions from the Class XII syllabus and 14 from Class XI. All the topics were not covered. Some questions were a bit confusing and the calculations were relatively tougher, which made paper somewhat lengthy. A few questions were straight from XIth standard topics. The rough space given in paper was less as compared to last year, making it rather cumbersome.

Mathematics was only slightly tougher than last year’s paper, but most of the questions required lengthy calculations. The good news though was that they were mainly dedicated to one concept only. There were 15 questions from the Class XII syllabus and 15 from Class XI. The Paper contained questions from most of the key topics.
