class XI and class XII almost equal parts in JEE main but for mathematics 12th class is some higher weightage as well as chemistry , for Physics it is almost similar.

Four important topics in mathematics you should focus on co-ordinate geometry, most of the part of co-ordinate geometry airport in the class 11th like parabola ellipse hyperbola and these are very important from the point of the name also you should give importance to quadratic equations sequence and series functions. PhysicsPhysics you should focus on rotational dynamics waves . For Chemistry you should focus on chemical bonding thermodynamics equilibrium Redox reaction in basic organic chemistry this are very important topics from class 11th.
