How crack jee advance exam? What are the chapters that to be perfect without any fail yo get good marks for a obc ncl candidate?

Hello,

Since your question is about cracking JEE Advanced and its tips, I must say that it clearly depends upon you and how well you have prepared. Coming to the topic, in Physics you should be good at Electrostatics and related topics and Modern Physics. These chaoters aren't much time taking, good to grasp and there are usually many questions in JEE Advanced from these topics. You can not really pick one topic from Chemistry but still try to revise all the formulas of Physical Chemistry, go through the mechanisms of Organic Chemistry throughly and revise Inorganic important topics quite regularly. In Maths, practice as much as you can, specially in Calculus, Vectors and three Dimensional geometry. These are the topics with very much weightage in JEE Advanced. But please note that these are only the very important topics. Questions can be asked from any topic so it is better to be prepared for all the topics you can cover rather than just looking at some. The above mentioned topics have more weightage hence I consider them very important.

Hope this helps.
