Give me chapter wise weightage of jee adv 2018

JEE Advanced focuses on a lot of topics. All topics are important. The most important ones include:



MATHS



1)Conic Sections,3-D geometry and Vector Algebra (Analytic geometry)- This is one of the most difficult topics in maths and they like asking difficult,time consuming question from this topic.



2)Calculus-Limits,differentiation, integration etc. This is one of the major chunks of the maths syllabus. Very important. Definitely , questions come from this topic every year.



3)Trignometry-Again ,a very important topic.



4)Probability,Matrices and Binomial Theorem -These topics are important and useful for engineering ,so questions can be expected from them.



5)Algebra and Complex analysis -Another big chunk of the syllabus. They like asking questions related to logarithm,quadratic eqns, sequences and series etc. Complex analysis is also important ,especially with respect to geometric interpretation of complex numbers.



PHYSICS



Mechanics



Mechanics is probably the most important topic in physics from JEE perspective. A bulk of questions in JEE are either directly mechanics questions or require you to have considerable skill in mechanics, which will help you solve a part of the question.



There are some of the most fundamental laws  Newtons laws of motion, universal law of gravitation, the law of conservation of linear momentum and so on. You must know how and when to apply formulas and these laws properly.



Some of the problems also requires basic calculus knowledge, so take care of that part too.

Study fluid mechanics, Bernoullis equation, elasticity seriously.



Electrostatic current and magnetism



This is another big section of JEE and among the most important chapters for JEE. A lot of questions are asked from the applications of Coulombs law and Capacitance. Stick to the JEE syllabus because this topic is diverse.



Dont be scared of complex circuits and try to use the fundamentals to reduce complicated circuits to simpler ones. Use Kirchhoffs laws, series parallel reduction and such tricks. Do not ignore the theoretical aspects of the topic. There are quite a large number of standard formulae in electrostatics and magnetostatics. Make sure to remember them all (with directions involved) because you wont have enough time to derive standard results on D-day.



Motional EMF is one of the most asked topics and should be among the top priority chapters for JEE, so ensure that you practice ample of questions from it.



Thermal physics and soundwave



This chapter covers a big chunk of the paper too. Since the topics are diverse, dont be surprised to see a question which is a mix of calorimetry with the laws of thermodynamics. Familiarize yourself with calculations of work, internal energy and heat in various processes.



A lot of questions are asked from waves and sound; the most common ones are from Doppler Effect.



Optics and dual nature



Optics isnt as difficult as it seems; it is indeed one of the easiest topics for JEE. Practice many questions, and youll be able to master it. Do not ignore Huygens principles.

Modern Physics is mostly theoretical. In this, the focus should be on understanding the nuances of Bohrs model. The common formulae should be memorized.



Experiment



JEE Advanced also contains problems related to experiments like error analysis in vernier callipers, screw gauge, and questions from potentiometer. So, practice questions from these portions.









Physical chemistry



Physical chemistry has nothing difficult in it. Its all about understanding the concept and applying formulas at correct places. All simple. Understand Mole Concept and topics like Chemical Equilibrium, Chemical Kinetics, Electrochemistry are all derived from it, and you will find these topics easy.



Put some efforts in understanding Thermodynamics and atomic structure by solving problems.





Organic chemistry



The key to understanding the entire organic chemistry being thorough with the general organic chemistry section  electrophiles, nucleophiles, types of reaction, acidity, basicity, etc. The remaining organic chemistry is just the application part.



E.g. Knowing that a reaction consists of a nucleophile attacking an electrophile; the only remaining bit is writing the mechanism.



Named reaction



A large part of organic chemistry consists of standard named reactions and students are expected to know these reactions along with the mechanisms. It is always good to know the mechanism of a specific reaction so that you can solve a similar new problem. Still, you should learn and memorise all the named reactions with exceptions too (exceptions are also very important!).





Inorganic chemistry



All the chapters of inorganic chemistry are very important. Please read all the chapters from NCERT at least 5 times line by line. Many questions are from p-block, making it the most important chapter. Read from chemical bonding to s,p,d,f block to metallurgy. There will be one question at least from each chapter.



A good knowledge of periodic table and the trends in the properties of atoms (ionization potential, atomic radius, electronegativity, electron affinity, electrode potential) will help you to understand the reactions.
