Dear vineet

In a exam like IIT JEE you can't leave any topic.

if you will see the pattern of last year papers,then you will find that question were framed in such a way that it include more than one      chaptre. and in whole paper almost entire syllabus are covered .so it is not advisable to leave any topic.

but you should give more stress to perticular topic which has been given more waitage in last few years in IIT JEE paper.

  calculus, Vectors, Complex numbers, co-ordinate geometry(2D+3D) Quadratic equations.

The more topic you will leave less marks you will get.
