Mechanics

Physics and measurement

This includes the topics of units,errors and measurements dimensional analysis etc. when we read the syllabus of jee main and advance it looks different but list of experimental topic is different so match the syllabus before picking experimental topic. This is a very smallest topic and the weight-age of this topic is an average of 2 to 3% in iit jee advance.

Kinematics

Difference of syllabus in this topic is vectors while if we read the syllabus of jee main many things that are seen from “frame of reference to uniformly accelerated motion” all this is basically a part of kinematics in one and two dimensions as mention in jee advance syllabus. Jee main syllabus gives more idea about the topic on which we should focus the study. In the topic of vector we do not need special study because it is also in maths.But in case of relative velocity problem student messes up in the exam so learn the voice post for that and video on it below. Student can expect one problem from the topic of kinematics in jee mains and advanced.

Laws of motion

In the topic of laws of motion all is same but jee main syllabus mention rolling friction which is not in jee advance syllabus and this is not an issue because it is just a small theory part not any numerical going to appear in exam on this topic. The topic of equilibrium of concurrent forces is mention in jee main syllabus it is basically a portion of statics and no cause of concern because it is also in maths of jee main. The topic of Laws of motion and friction have a share of 4% in jee main and advance exam.It is simple topic but coaching classes wastage much time on it to teach.It can be prepared in 3 to 4 days for iitjee if concepts of laws of motion and maths are cleared.

Work, energy and power

In the topic of work energy power so many small things have to study and syllabus of both jee exams is same although it looks different and better listen the voice post on it. The topic of Work energy power is small and its very simple to understand and its very useful in all the parts of physics. Student should do it very good even it has small share but very useful to solve the problems of physics.

Rotational motion

From “rolling without slipping to collision of point rigid bodies” part of jee advance is mention properly and differently from jee main syllabus while other is same and this part also may be asked in jee main and nobody can call it out of syllabus since it is mix of many things of rotational motion. This topic is asked in jee advance since many years so do not leave it and study it before jee main. The average weight-age of Rotational motion is 6% in iitjee physics paper and regarded as most difficult topic by students and teachers. The topic of rotational motion is asked almost every year in iitjee exam. It is a must do topic and it needs many concepts and practice of many types of problems.

Gravitation

Except Kepler’s law which is mention in jee main syllabus but not in jee advance syllabus all the topics of gravitation chapters is same. Kepler’s laws are three small theoretical points only just read down. The topic of Gravitation is covers an average of 2-3 % in iitjee exam and it needs the knowledge of work energy and rotational motion as compulsory to solve problems in iit jee paper.


Heat and thermodynamics and GPM Properties of matter

The Hooks law and Young modulus is mention only in Jee advanced syllabus, and the bulk modulus and modulus of rigidity is mentioned in jee mains syllabus. For jee advance only hooks law and young modulus will need to study. Also in surface tension topic which jee main syllabus mention clearly are drops and bubbles in application of surface tension and it is also a part of jee advanced even if not mention problem may be asked. The topic of fluids Reynolds number mention in jee main syllabus but not in advance syllabus it is a small topic and need not to be leaved.

Thermal physics

The topic of temperature is mentioned in jee main syllabus. It is very important to note that jee advance syllabus includes black body radiation and associated laws like kirchoff’s and wein’s laws, stefan’s law very clearly and better study it before jee main because jee main can ask anything out of it although it will be better to see past year papers very carefully before to go deep in any topic. The general properties of matter like elasticity, viscosity, surface tension and fluids covers an average of 5% in iitjee exam and said to be easiest topic except Bernoulli’s principle.Even if it is small and simple topic.

Thermodynamics Heat work and first law of thermodynamics is the topic of Jee main syllabus not in jee advanced. This topic covers an average of 10% in IITJEE exams. The topic of thermodynamics and radiation conduction etc.is the best source of marks in the iitjee mains and advanced.these topics are very simple to prepare and never complicated to solve any problem so student must do it very well.

Kinetic theory of gases

In IITJEE mains and advanced the topic of Ideal gas equation work done on gas is common but the topic of kinetic theory of gases is completely missing in jee advanced syllabus. It is best for student to study it for jee mains and then in jee advanced they need not to take much care of it,if concepts are cleared then there will be no problem will occur in jee advance. To understand the Concepts of this topic is needed to solve problems of thermodynamics in some cases so formula of Cp, Cv and related must be remembered.


Waves and SHM Oscillations and Waves

All the parts of waves and oscillation topics of jee advance syllabus is in jee main and following topics are extra mentioned for mains exam syllabus. These topics are periodic motion,free forced and damped oscillations,reflection of waves,fundamental mode and harmonics etc.So best to do these extra topics just before exam and if forgotten after main no harm will be there. With about 10% share in physics paper shm (4% share) and waves (6% share) is difficult topics and requires knowledge of almost entire formulas and concepts of physics to solve problems from it also it is has many formulas.


 Electricity and magnetism Electrostatics

The chapter of Electrostatics 1 and 2 is already in jee mains syllabus and topic of dipole mentioned in jee mains syllabus is in more detailed manner but it is all small and easy to remember topic and can be asked in advanced as well. The topic of conductors, insulators, dielectrics and electric polarization is in jee mains but not in advanced. The part of electrostatics covers an average of 7.5% in iitjee physics paper.It is a very conceptual topic with many calculations,this topic has many formulas and needs very neat calculation based on many concepts.

Current electricity

The topic of current electricity includes many points in jee main which is not in jee advanced syllabus. These topic are drift velocity,resistance of materials,V I characteristic,color codes,temperature dependence of resistance,electric cell,emf of cell potential difference etc. Wheatstone bridge potentiometer,Meter Bridge etc. All of advance syllabus is contained in jee main syllabus including heating effect of current which is not mentioned in jee main. the topic of Chemical effect of current and thermo emf is not in any syllabus. The weight-age of current electricity is 5% in iitjee advanced and it is a very simple topic and the marks can be obtained easily.

Magnetic effects of current and magnetism

All the points of magnetic effect of current and related topics of jee advance syllabus is in jee main as well including the force between parallel wires which is not mentioned in jee advance. The topic of magnetism is start from bar magnet to permanent magnets is in jee main syllabus only and need not to do for jee advanced. The average weight-age of Magnetic effect of current and magnetism is 6% in iitjee physics paper. The magnetic effect of current and magnetism is a very conceptual topics,which requires a good mathematical ability to solve a problems.

Electromagnetic induction and alternating currents

Electromagnetic induction and alternating current is almost the same topic.the topic of alternating current mention many small terms like quality factor,resonance and power in jee main syllabus and its easy and long lasting from memory while alternating current generator and transformer is only in jee main syllabus so can be left without any tension. The average weight-age of Electromagnetic induction and alternating current is 6% in IITJEE physics paper and it is some easy than electrostatics but difficult than current electricity. This both the topics require very good concepts with sound mathematical ability.


Ray optics wave optics

All Ray optics points of iit jee advance is in mains as well but jee mains includes optical instruments which is not in jee advanced syllabus so leave it for the time of jee advance. The topic of Ray optics is common in both the exams of iitjee mains and advanced but from “diffraction” to “Polaroids” jee main syllabus have many points that are extra from jee advanced syllabus. The weight-age of ray optics is 12.5% in IITJEE physics paper. Ray optics is the best topic to get good marks in iitjee physics paper after modern physics and thermodynamics. It requires a good knowledge of simple geometry only and only few formulas are there to memorize and apply in a problem.

Electromagnetic waves The topic of Electromagnetic waves is in jee main syllabus only.


Modern Physics

Dual nature of matter and radiation Except Hertz and Lenard’s observations and Davisson Germer experiment this portion of modern physics mentioned equally in both exams syllabi. No one should leave Davisson Germer experiment it is very good topic to asked in jee advance in passage based problem. While X-ray and moseley’s law is in jee advance only. With 10% of weight-age of jee physics paper modern physics is the best to score marks faster with sureity in iit jee.  

Atoms and nuclei Except Rutherford’s model of atom all of jee main syllabus of this portion is in jee advance syllabus. Many questions asked With a special emphasis for energy calculations in nuclear process in jee advance, which is asked in almost all past year papers. With 10% of weight age modern physics is one of the best to score.

Electronic devices This topic is small and contains mostly theoretical concepts and many small points to focus. One question can be expected and it is not going to be asked in jee advanced it is in jee main syllabus only.

Communication systems It is basically a topic of ncert school syllabus and it would be better to prepare from ncert book and this is big chapter of difficult things so better to study superficially and it is not asked in jee advanced exam.


Experimental Skills This is most important to see a practical book to prepare for experimental physics questions asked in iit jee advance. And it is also needed to refer a good theory book that will help to prepare this topic properly. This portion has less than 20% weight-age in jee mains but when if we see the papers this is actually the number of question is less than expected. And also in jee advanced 2-3 simple problems are asked so far so best to prepare it properly.
