Important Topics: There were 2 questions each from Application of Derivative, Binomial Theorem, Coordinate Geometry (3D), Matrix & Determinants, and Sequence & Series in JEE Main paper held on April 4.
Less important Topics: No questions were asked from Differentiation, Sets and Relation, Trigonometric Equations, and Trigonometry Ratio & Identity in April 4 exam.
This year, Mathematics section was quite easy as compared to previous years’ JEE papers. There were 14 easy questions and 14 questions with medium toughness level. Only 3 questions could be said to be difficult. However, the paper was quite lengthy and students who knew shortcut methods well would have had an edge over their peers in the exam.
