Hey, the JEE (Mains) exam consists of three sections- 1.Mathematics   2.Chemistry  3.Physics and in order to get good score in JEE (mains) you have to excel in all the three sections.

The Mathematics Syllabus for JEE mains is:

Quadratic Equations, Sets, Relation and Functions, Matrices and Determinants,  Permutation and Combination,  Limits-Continuity-Differentiation,  Calculus(Integration),  Differential Equation,  3D Geometry, Binomial Theorem with its applications ,   Sequences and Series ,   Vector Algebra   , Statistics,   Trigonometry and   Coordinate Geometry.

Master all the these topics with a proper study plan and please do not forget to give equal attention to the other two sections as all the three sections make the composite score and the High you score in each section higher will be the chance of getting a reputed college .

Be stress free and Plan it well.

All the best !
