Which are the most important topics to focus in JEE?

Question

Atul Mehra · Answer

As for JEE, it includes at least one problem from every chapter in the NCERT syllabus. As for important topics, there is no such thing. All topics in your book are equally important. That being said, I would cite some examples. At the beginning of class 11, Mechanics hit full gear in Physics. You would find all study materials rife with rotational dynamics problems. If you go to school or coaching classes, students are breaking sweat over moving pulley problems. Typically it takes about 7-8 months of thorough preparation to complete Mechanics from HC Verma, Resnick-Halliday, Irodov, RSM or some other study material. Now, go and check the number and difficulty level of Mechanics problems asked in JEE in past 10 years. It really feels like all that effort was nothing, innit? Instead, you would find problems on Modern Physics and Optics or even Electrodynamics more in number. However, to understand Mechanics fully with all concepts thoroughly covered and practiced - you need that long term effort. Similarly there are other topics that students find very interesting, get attached with easily. For example, Permutation-Combination, Organic Chemistry, Quadratic Equations and Theory of Equations, Newton's laws of motion, Trigonometry, Indefinite Integrals, Periodic Table and Chemical Bonding etc. It's laudable to spend lot of time in these and master them. Unfortunately, most students make the common mistake of ignoring the other seemingly bland topics such as Inorganic Chemistry, Ores and Metallurgy, Stoichiometry, Ionic Equilibrium, Matrices and Determinants, Coordinate Geometry, Functions, Definite Integrals, Modern Physics, Errors in Measurements, Solid-state chemistry, Sound and Waves etc. And since quite a good number of questions are asked from these sections; it's prudent to devote enough time to prepare these sections.

JEE is one of the tough exams in India so result varies from student to student:- 1. Many want to be top in the exam 2. Many want to score decent marks 3. Just cross the cutoff marks For the first category student, you need to study all the syllabus in the proper manner so that you can be top in JEE exam. For the second category student who wants to score decent marks and want to get into atleast NIT college then, in that case, don't leave topics like:- Chemical Bonding, Atom, State of matter, Thermodynamics, Hydrogen, S&P Block elements, D block elements, Solid State, Solution, Chemical Kinetics, Alkane, Alcohol & Ketone Biomolecule. In Physics Law of motion, Work energy & Power, Gravitation, Sound, Electricity & Magnetism, Optics, Modern Physics. In mathematics subjects like Vector, 3D Geometry, Straight line, Differential Equation, Circle, Parabola, Ellipse, Hyperbola, Andhra Pradesh&GP, Limits, Matrices, Probability These are enough to score decent marks in JEE exam. For the third category, student chooses the topic which is easy for you. All the Best to all category student.

In physics and chemistry, it is very important for JEE exam. There are more confusing questions from these subjects, so these subjects should be concentrated more.

Hi, There are some topics which are the most important and scoring topics. A firm command over these topics will surely boost your rank. Physics : Kinematics Very simple questions are asked. If you keep the definitions in mind, then all questions will be easy Newtons laws of motion Knowing how to draw a free body diagram will greatly help in solving almost all problems of this chapter Simple harmonic motion Energy conservation method will be useful in finding time period in even the most complicated cases of SHM First law of thermodynamics Knowing the statement of energy conservation will help you to solve a number of numericals and theoretical questions as well Current Electricity A good practice of Kirchoffs law problems will help you to score cent percent in this topic Radioactive decay The radioactivity decay formula will be the most useful tool in solving almost all the problems Mathematics : Conic sections Knowing the formulas well will help you. The parametric form is one of the most useful tool in solving problems of conics Quadratic Equations knowing the fundamental properties regarding nature of roots / intervals in which roots lie will help you Progression and series very scoring and simple chapter. Knowing the definitionsand practising ample of problems would be useful Differentiation Keeping the formulas in mind will help. Geometric interpretation of derivative is an important concept. A number of simple questions are asked which can be done with ease Vector Algebra Knowing how to visualize the situation will be useful. The concepts of vector and scalar triple products are most scoring Chemistry : Alkyl Halides Simple questions based on reactivity / type of reactions are asked and can be cracked easily Electrophilic aromatic substitution reactions of benzene standard reactions are the most important. Direct questions are asked from this chapter Chemical Equilibrium - Knowing the basic equation of equilibrium along with a proficiency in solving ideal gas equation problems will definitely fetch you full marks Chemical Kinetics First order reactions are asked in JEE and are easy if you know the basic definitions Ores and Metallurgy - Standard questions are asked which can be done easily Coordination compounds - isomerism is an important but easy topic and you can easily score 100% in this These are just the few important/scoring topics. Ideally you should try to cover the entire syllabus well. Focus on these topics. All the best

The chapters for JEE are stated in a subsiding priority order, which means the ones at the top have the top priority and priority level reduces as you go through the list. 1. Physics: Physics needs you to have a robust hold on concepts. Once the concepts have been grasped, they are very easy to retain. Some chapters for JEE from physics have a substantial weightage in the exams. 2. Mechanics: Mechanics is perhaps the most significant topic any engineer should know. This always makes it the most vital part of the paper. Indeed, the majority of questions in JEE are either directly mechanics questions or need you to have substantial skill in mechanics, which will support you solve a part of the question. Also, do not ignore the chapter on elasticity. 3. Electricity and magnetism: This is added as a big section in JEE and one of the essential chapters for JEE. A lot of questions are asked from the applications of Coulomb's law and Capacitance. Stick to the JEE syllabus as this topic is diverse. Don't be afraid of complex circuits and try to use the fundamentals to lessen complicated circuits to simpler ones. Use Kirchhoff's laws, series-parallel reduction, and such tricks. 4. Thermal physics: This chapter covers a big chunk of the paper too. Since the topics are diverse, don't be surprised to see a question, which is a mix of calorimetry with the laws of thermodynamics. Acquaint yourself with calculations of work, internal energy and heat in various processes. -Fluids and waves and sound -Potentiometer-related experiments -Optics -Modern physics 5. Chemistry: One must understand that it's very significant to read as much as possible in order to learn chemistry. Also, revision is essential as there's a prospect of forgetting things. Take chemistry as seriously as mathematics and physics. Do not ignore this subject just because you feel chemistry is purely cramming. 6. Physical Chemistry Mole Concept: The most important and central concept in physical chemistry is the mole concept, which lies at the heart of the subject. Hence, it is certainly one of the most significant and basic chapters for JEE chemistry. 7. Atomic Structure: This is the only chapter whose contents do not seem to have a direct correlation to mole concept. Questions from atomic structure are regularly asked in JEE. 8. Other topics: The rest of physical chemistry is basically derived from mole concept. Other concepts like Chemical Thermodynamics, Chemical Equilibrium, Chemical Kinetics.

I read an article on Topper which was about how you should prioritize the chapters you study. So here it is: Physics: Physics requires you to have a strong hold on concepts. Once the concepts have been mastered, they are very easy to retain. Some chapters for JEE from physics have a heavy weightage in the exams. Here's the priority sequence you can follow chapter-wise: Mechanics Electricity and magnetism Thermal physics Fluids and waves and sound Potentiometer-related experiments Optics Modern physics Chemistry: One must understand that it's very important to read as much as possible in order to learn chemistry. Also, revision is crucial as there's a possibility of forgetting things. Take chemistry as seriously as mathematics and physics. Do not ignore this subject just because you feel chemistry is purely cramming. Weightage is nearly equally distributed in the three streams of chemistry. It is important not to skip any topic from Inorganic chemistry as the subject is highly scoring. Physical Chemistry Mole Concept Atomic Structure Other topics: Organic Chemistry General Organic Chemistry Named Reactions Organic Synthesis: Inorganic Chemistry Everything is Important Mathematics: For mathematics, you need rigorous practice. The more problems you will solve, the better will be your speed and accuracy.

Kundan Singh · Answer

If you want to crack JEE with flying colors then you must have to focus on the whole syllabus. However, if your goal is to crack JEE and rank doesn't matter much then you have to focus on few topics. Some topics are important but difficult to understand. Rotational dynamics is one of them. I think important means easy as well as scoring. Let me tell you some subject wise important topics: 1- Maths: Algebra, coordinate geometry, vector, and 3-D, probability calculus, etc. 2.Physics: Optics, current, and electricity, simple harmonic motion, kinematics, etc 3.(a) Organic chemistry: Whole NCERT is enough but you should not skip any topic of NCERT. JEE ask some direct questions from it. (b).Physical chemistry: Mole concept and stoichiometry, redox reactions, chemical and ionic equilibrium, electro chemistry, etc. (c). Inorganic chemistry: Coordination compounds, P, D and F block elements, Atomic structures. etc. Again NCERT is enough for inorganic chemistry as well. If you have enough time then you should focus on work, power and energy, permutation and combination, rotational dynamics, etc. I hope it will help you.

Hi, I would personally advise you to complete and revise your entire class 12th syllabus and specially from NCERT books. Coming to your question about the most important topics, below are the important topics (subject wise) which can help you to score high. Chemistry: p Block Elements Coordination Compounds Biomolecules and Polymers d and f Block elements Chemical Bonding and Molecular Structure s Block elements ( Alkali and Alkaline earth Metals) and Hydrogen Electrochemistry Chemical Kinetics Atomic Structure Alkanes, Alkenes and Alkynes ( Hydrocarbons) Physics: Properties of Matter and Fluid Mechanics Electrostatics Semiconductors and Communication System Electromagnetic Induction and Alternating Current Ray Optics Magnetic Effects of Current Laws of Thermodynamics Current Electricity Atomic Structure in Modern Physics Maths: Trigonometrical Ratios, Functions and Identities Sequences and Series (Progressions) Vector Permutation and Combination Statistics Parabola Definite Integration Circle Indefinite Integration Binomial Theorem Quadratic Equations JEE Main Topic Wise Analysis Physics: Though there is no pattern that JEE is following here but you can see that topics like Modern Physics, Optics, Heat and Thermodynamics,Electrostatics , Magnetism & Magnetic Effects of Current, EMI & AC Circuits and EM Waves have been scoring topics in decreasing order. Chemistry: In average General organic chemistry + Functional Group I has most questions (avg=5.5) but JEE 2016 had only 2 questions from this topic, apart from this Coordination Compounds, Atomic structure, Chemical Thermodynamics, Organic Chemistry Functional Group III, Chemical and Ionic Equilibrium,States of matter,Bio-molecules, Chemical Bonding, Functional Group III are topics in decreasing importance according to the data. Maths: In Mathematics Application of Derivatives, Indefinite Integrals, Definite Integrals & Area under the curve, Matrices and Determinants, Probability, Quadratic Equations, Inequalities, Progression are important topics in decreasing importance. Wish you all the best for JEE Mains and Advanced both.

archit kumar · Answer

Hi there, Well there is nothing like more or less important topics in JEE,however some of the insights of the topics are. For maths- calculus, coordinate, matrices and determinant,vector & 3d,probability. Organic- revise ncert thoroughly. I think none of the organic part should be skipped. Inorganic - p,d,f blocks and chemical bonding. Physical -kinetics, thermodynamics and equilibrium (ionic equilibrium is must) small chapters like solid state, mole concept and solutions can fetch you good marks. Physics- modern physics, shm, waves, electrostatics and current & optics. Hope it helps.
