Physics was my favorite subject. I was initially pretty weak at physics (the mechanics part). But in class 12th, I came across one of my teachers who changed my perception about Physics. He supported me a lot and it was because of his support/guidance that I was able to crack INPhO and was also selected to represent India at the 14th Asian Physics Olympiad, Indonesia in the 8 member team (although I didn't participate in it because it's date clashed with JEE advanced registration dates).
No doubt, HC Verma is the best book for Physics.
Physics can be broadly divided into the following parts:
1.)Mechanics : for this, HC Verma is the best (along with
NCERT) for theory and for practice, IE Irodov is the right book. You can also try DC Pandey. Mechanics requires intense practice and good exposure to a number of questions. It is one of the most scoring part of JEE Paper.
2.)Thermodynamics : Again, for this part, HC Verma is sufficient. From this part there will be around 3-5 questions in the JEE paper.
3.)Electricity and Magnetism : For this part HC Verma is not enough. You need to go beyond that, because in JEE, there will rarely be any straight - forward question from this part. Having a command in this part will definitely give you an edge over others because it has a huge weightage in the JEE paper.
4.)Optics : One of the easiest branch of Physics if prepared well. Most scoring and easy to grasp. But, beware - this part has the widest scope of silly - mistakes. Sign convention must be kept in mind otherwise the question is bound to go wrong.
5.)Modern Physics : Tough nut to crack. Difficult, quite theoretical. This part, besides numericals has a lot of theory based questions. So prepare well especially the Radioactivity and the X-Ray part. HC Verma and NCERT must be thoroughly covered for this section.
To summarize, HC Verma is the best book for Physics. But don't ignore NCERT. Read complete NCERT atleast 2-3 times. You will definitely find something new.
If you simply study Physics, then it isn't going to work. You need to feel it, enjoy it and more than that apply it.
Another good one..
ReplyDeleteHoping the next post is about maths and comes early
hello aman bhaiyya..
ReplyDeleteyour posts are really good
please continue writing
you are an inspiration to me
did you use any book for theory(physics) by any foreign authors?
ReplyDeleteNot exactly. But resnick Halliday book was useful in the beginning
DeleteMy fiitjee teachers recommend to use pradeep's fundamental physics but Raghu mahajan'(AIR-1 in IIT - 2006 and AIEEE- 2006) says in his blog :- The Blacklist of Publishers: If you are reading a book by any one of these publishers, you are probably not on the right track: Pradeep, Krishna, Modern’s,Gupta and Gupta. These books are literally trash and should not be read by anyone.
DeletePLEASE SUGGEST WHAT SHOULD I DO?
HC Verma + NCERT + Resnick Halliday(Only if required) that's it.
DeleteFurther , You may refer to DC pandey (Arihant) books for good questions.
I have no information about the book that you mentioned.
If you want then I can provide you reviews from many top rankers of IIT JEE who are in IIT Bombay (atleast the 42 top 100 rankers in Computer science branch). That's all I can do.
This comment has been removed by the author.
Deleteyes sure,u can provide me reviews from top rankers of IIT JEE who are in IIT Bombay.
DeleteHalliday resnick international student version or jee edition?
DeleteHalliday resnick international student version or jee edition?
DeleteCan u please suggest a good book for rotational mechanics?i have done fiitjee's package but still i feel i'm lacking confidence in dis topic...
ReplyDeleteTry hc verma/old Arihant book.
ReplyDeleteThe old Arihant book is better than the new one
I would recommend solving this chapter from irodov.
It's a really good book for mechanics.
People think that it contains too difficult problems, far beyond human approach but if your concepts are strong then you will enjoy this book
THNXX
Deletebrother i have the book from cengage series[author is B M SHARMA].is that enough or should i get the new one i e irodov`s book.
ReplyDelete@Sai: I haven't heard of that book so I can't say anything about it.
DeleteBut irodov is a really good book.
It has remained the choice of jee rank holders from years
In Bm sharma itself many irodov questions are there which are based on iit pattern..and this book contain more than 500 questions in each chapter..
Deletebhaiyya..i would like u to share http://www.physicsgalaxy.com/# on ur post....Lectures on this website are by Mr. Ashish Arora(centre head and head of dpt.physics)at fiitjee jaipur centre...He has been guiding students for various competitions in India since 1992. As Physics mentor for International Physics Olympiads, he has an outstanding track record.several of his students have won the coveted prize besides securing top 10 ranks in the prestigious IIT JEE.
ReplyDeleteEven I have heard about him.
DeleteThanks for suggestion.
I'll update the post soon.
tht helped a lot thnx.. i was really luking for sum lectures on radioactivity.. :)
Deleteand bhaiyya please also tell u used which book out of the following:-
ReplyDeleteunderstanding physics for jee by DC Pandey(which contains theory and question) OR Practice book of physics by DC Pandey(which contains only questions)
The book-understanding physics for jee by DC Pandey(which contains theory and questions) is a good book and is used by a number of Jee aspirants.
ReplyDeleteAlthough I Didn't use the book in detail. I solved mechanics problems from the old edition of the same book(which contains really good subjective problems)
U mean that u bought DC Pandey-mechanics part only.. and no other parts like electricity & magnetism/waves & thermodynamics etc. etc.??
DeleteCorrect. I bought the book on electricity and magnetism too. I used it initially but later on stopped using the book because I found my teacher's sheet more useful.
DeleteHowever I would still recommend you to use the book. It's good.
hey i have just had a look at irodov's questions and i feel that they are actually different from jee questions.
ReplyDeletewhat is your take on this ?
are there top top 50 rankers you may know of who have got the top 50 rank without irodov , solely depending on their coaching material(fiitjee in my case ) and hc verma ..?
yes there are friends who never picked up irodov
ReplyDeletei can bet - all top 50 rankers have 50 different types of preparation strategies.
so you can't just say - "with irodov or without irodov"
if you wan't to get a grip over the subject then go for it (it's the best book available) and believe me - solving this book is going to make your confidence sky high.
however if you feel that you are unable to do the problems then leave the book and try some other book
Hello Bhaiya!!!!!!!
ReplyDeleteI am a JEE 2014 aspirant. I have completed most of the topics in physics from my side but I am still not getting confidence in some topics. Should I try Irodov at this stage or do something else?
You should not move to irodov because problems of irodov are really tough and it would be useless to try that book without having a firm grip over the subject.
DeleteTry hc verma and Arihant(dc pandey)
Thank You Bhaiya!
DeleteWhich material would be good for waves?
ReplyDeleteWhich one did you use?
thanks in advance for ur reply!!
Well waves is something I am still scared of
ReplyDeleteof.
We have a quantum physics course in our first semester wherein we are supposed to find out the wave function in various cases by solving the famous shrodinger equation and I am horrible at that.
Anyways hc verma is a good option.
For practice, fiitjee material is good enough.
If you can anyhow get Bansal's material then that's the best for waves
Are you referring to the target batch material or tbe current material (i mean 2019-2020
DeleteThanks man!!
ReplyDeleteOut of the 2 (HC Verma or DC Pandey)
ReplyDelete->which source is good for some difficult problems
i.e.,solving which one will be equivalent to the JEE "LEVEL"
(very fundamental but with a little difficulty) questions ??
Or else please suggest any other good source which contains only questions of the JEE difficulty level !!
PS: Thanks for your reply on my query on waves and one more thing to remind you about your "D-day" post for which all the JEE aspirants are waiting eagerly...
Thanks in advance!!
See the level of paper varies a great deal.
DeleteFor example JEE 2013 contained one of the easiest physics portion in the history of JEE. Many people managed to score above 100/120 in physics.
But in some years it's not that easy so you need a rigorous practice.
That's why taking a risk is not advisable and it is recommended that you prepare for all circumstances.
For this, irodov is the recommended book.
You should solve a number of subjective problems. It will definitely be useful because these days what is done is that objective questions are framed from the subjective questions.
Neither dc pandey nor hc verma can guarantee a good score.
But irodov will do so if you solve it earnestly.
Else in the end for tougher level of objective + subjective problems, go for fiitjee Gmp. It's the best for physics.
And also note that I was good at physics (113/120 in JEE) so I could handle irodov and GMP well.
In a situation where you are not comfortable with either of the two, leave it and go ahead with hc verma or dc pandey.
You do not want to get outstanding score in physics and extremely poor scores in the other two.
This answer has been written keeping in mind that u r a JEE 2014 aspirant.
And thanks for reminder.
Thank you for your valuable reply!!
Deleteand you guessed it right that i am an aspirant taking JEE on 2014!!
PS: can we solve irodov for all the branches of physics or should we stick to only mechanics and electricity magnetism
(i.e., is it good also for waves,thermodynamics,optics and modern physics as well)?
Thanking you in advance and a very Happy New Year!!!
Keeping in mind you have limited time in hand, you only need to solve selected problems of irodov that too of mechanics, electromagnetism and thermodynamics
DeleteI didn't solve other chapters because they are not relevant to JEE
Keep in mind that if your syllabus is still not completed then don't do irodov.
Complete your syllabus first and solve more of objective problems.
Irodov is something that is to be done when there is enough time in hand and is done parallel to the chapters
Thank you!!

ReplyDeleteHELLO.BHAIYA CAN U PLZ TELL ANY BEST BOOK FOR FULL ELECTRO & MAGNETISM WHICH HAS BOTH CONCEPTS AND ITS APPS.
ReplyDeleteDc pandey is good + hc verma
DeleteThis comment has been removed by the author.
ReplyDeletehey aman...is hc verma and ncert enough to fulfil the theory purpose for iit jee?? if not..what else do we need??
ReplyDeleteFirst of all define enough
DeleteDoes "enough" imply just selection in JEE or a 4 digit rank : yes then enough
Does it imply a 2 or 3 digit rank : no not at all enough.
If we tend to aim for a 2 or 3 digit rank..then what else should we use for theory purpose..not questions but theory only..ie. to learn concepts..??
DeleteIf you are for JEE 14 then stick to problem solving. Nothing new now.
DeleteIf you are a JEE 15 aspirant then purchase "Resnick Halliday ".
It's really good for theory and for self study
Note that the problems might not be that good because they are long and descriptive. However some problems are super good.
In short, it's the best book for learning physics through self study but you have to be smart about how to make the best use of it without diverting from JEE syllabus.
being a JEE 15 aspirant..for 2 digit rank..can we say that fully devoting ourselves to ncert+hc verma+resnick halliday+ie irodov is sufficient for both theory and questions purpose??
DeleteAgain it all depends on how well you are able to use these books.
Delete99% of the JEE aspirants use the above mentioned books (and almost every student in Kota)
But only a handful of them qualify the exam so not just the resources matter, but also how well you utilize your resources.
Bhaiya Halliday resnick international student version or jee edition? Thanks on advance
DeleteThis comment has been removed by the author.
ReplyDeletehey aman i have pretty much completed hc verma thoroughly done some problems in irodov mechanics what more should i do to get a good score say equivalent to 100/120 in jee 13 thanking you
ReplyDeleteTry covering DC Pandey books
ReplyDeleteHI! PLZ SUGGEST ME SUITABLE BOOKS FOR JEE MAINS FOR PHYSICS AND ALSO FOR MATHS AND CHEMISTRY WHICH MUST COVER ALL PORTIONS.AND FOR PHYSICS, IS FUNDAMENTALS OF PHYSICS(halliday and resnick) A GOOD BOOK.
ReplyDeleteBooks for JEE main :
DeletePhysics -> NCERT
Chemistry -> NCERT
Maths -> RD Sharma
Halliday is a good book but for JEE advanced. Use it mainly for theory purposes.
Hey Aman
DeleteI've just completed geometric optics from hc verma perfectly and im thinking of practicing it from dc pandey
will that be sufficient to perform well in the topic + should i practice questions of optics and electrodynamics from irodov???
HEY AMAN, IF U WERE SUGGESTING BOOKS FOR AIEEE, WHAT WOULD YOU SUGGEST?
DeleteNCERT
Delete@pranjul :
ReplyDeletewell you have completed enough but try to maintain this.
Revise the things by solving questions.
going further with dc pandey/irodov depends completely on you
yo bhaiya...didnt got any related query on my topic..
ReplyDeleteso i want to ask that when should 1 apply calculus in questions of physics???(i m not bad at solving calculus)
just getting confused that when these thing is to be applied....how to tackle this GRAVE problem????
and is there any basic(baccha type) book which can solve this problem???
JEE physics is expensively based on calculus.
DeleteYou should start it right from the beginning (from kinematics)
start with HC Verma problems
Hello brother...i have 2 questions.....(i am a 2015 IIT-JEE aspirant)
ReplyDelete1)i have started irodov...bt facing problems in some questions...lyk my ratio of soved to unsolved(need to see solution) is 60:40.....should i stick to it?
2)FIITJEE GMP+RESONANCE RB.....r these two the ri8 choice for revision for students AIMING FOR A 2 DIGIT RANK IN IIT-JEE??
P.S:-I AM AIMING FOR A 2 DIGIT RANK IN IIT-JEE...so i guess solving irodov is must.......
solving irodov is not at all must.
Deleteyou should be patient with that book.
If you really feel that it's a waste of time, then leave it.
GMP and RB are awesome
No no....i never feel solving irodov is wasting time....i enjoy it n physics is my favourite....its just that i was scared as i couldn't solve 40% problems in the beginning......
DeleteHello Bhaiya,
ReplyDeleteIt is usually said that Physics is a conceptual subject and one must be conceptually very clear. My doubt is whether we should concentrate more on Questions or on Concepts.
Both (or rather on conceptual questions).
DeleteYou won't be able to solve even the simple problems if you haven't understood the concept
You said for E&M HCV is not enough. Which other book did you studied for it then?
ReplyDeleteI had an awesome physics teacher who provided me ample of study material and problem sheets so I didn't have to ponder over books.
DeleteBut for you, you can go ahead with DC Pandey if you are facing any problem
Did you solved bansal sheets
Deletedid u do the other parts of irodov apart from mechanics?????
ReplyDeleteThermodynamics and some chapters of electromagnetism
Deletehow to strengthen up electomagnetism-i hav done hc verma and sum sums frm my coaching center.pls suggest a way
ReplyDeleteIE Irodov or DC Pandey
DeleteShould I read NCERT first or directly start HCV for Phy?
ReplyDeleteRead them parallely
Deletehi bro, i wanted to ask you that how is life in IIT. Is it a hard stressful life?
ReplyDeleteLife in IIT is extremely chill, at least in my first year.
DeleteI don't know about the coming years.
The first semester was a bit hectic because I took time to overcome homesickness and adjust in a new place with completely new friends.
But now since I am well settled here, I am enjoying this place.
Currently I have my exams going on but still, I am writing this answer. From this you can figure it out that how much time we waste.
Here have a look at it
http://www.quora.com/What-do-IITB-students-do-to-entertain-themselves-during-long-hours-of-study/answer/Aman-Goel-9?__snids__=327180783&__nsrc__=1
did you use some other books for topics like kinetic theory of gases, waves and sound, Optics and modern physics apart from hc verma, FIITJEE package and ncert.?
ReplyDeleteIf yes what are they plz give answer for this question by taking each topic separately that i mentioned above
No, I never needed books for those topics.
DeleteNeither did I rely on HC Verma.
Coaching material was more than enough.
My teacher used to cover all the topics in great detail so I didn't have to look for books.
However, if you are interested, then you may try DC Pandey books.
They are good and are meant specifically for JEE
How can we polish our mind?
ReplyDeleteTo solve problems.
Bcs when i going to solve tough problms than i have to go with thier solutions.
Than how can we able to solve such problms by own.
How can develop those ideas
It means that your concepts aren't up to that level.
DeleteStart from simple questions and understand the idea behind them.
A tough question is just a combination of these simple questions.
is cengage physics series by bm sharma relly useful or only some chapters....and how can i use ot to the best....!
DeleteNo idea
Deletei m 2015 aspirant..entering into 12th....how should i use resnick halliday for 11th class chapters..!
Deletei m 2015 aspirant..entering into 12th....how should i use resnick halliday for 11th class chapters..!
ReplyDeleteResnick and Halliday is a good book but only for theory.
DeleteQuestions from that book are not really upto the JEE level (Except possibly a few).
So you should read from that book (only those topics that are there in JEE syllabus) and understand the approach used for solving problems
bhaiya if u cud just specify some really gud chpt for it.
ReplyDelete& THANKS
I haven't tried much of it. But mechanics is good
Deletehello aman bhaiya......i am a jee 2015 aspirant .......i am going to bought dc panday of electricity and magnetism and of optics etc.........................................................please tell me which eddition is best...the new one or the old one..........and i had areday baught mechanics
ReplyDeletevol 1 new edition....should i change it to old one or this is enough......................please tell.....i hope u will rply soon.....
First of all, I am not Bhaiya. Call me Aman
DeleteThe new one is good enough for JEE. Old one contains a lot of subjective questions which may be useful for olympiads
Hey buddy......for NSEP & INPho preparation....there is a book in the market which contains a collection of previous years questions of NSEP...& INPho....at the same time there is also a problem book by KROTOV....containing some 250 questions.....which one should i go for?
ReplyDeleteP.S:I have IRODOV....bt are the NSEP/INPho/krotov problems better than IRODOV?
Krotov : I have heard a lot about this book but I haven't tried it.
DeleteI have been told that it's much much difficult as compared to irodov.
So I guess, it is not required because for INPhO etc, Irodov is more than enough
Hi AMAN,
Delete(I had an awesome physics teacher who provided me ample of study material and problem sheets so I didn't have to ponder over books.)
In one of ur answers u wrote that u were greatly supported by ur physics teacher because he used to provide u extra study material. But in fiitjee everyone receives equal no of cpps and sheets.
Can u please elaborate more on what kind of material he used to provide to u?
No. In FIITJEE, everyone doesn't get equal CPPs
DeleteHis classes used to be awesome. He used to provide us supplementary selected questions from good books
hey..!!..how is the book 'university physics by sears and zemansky'..??..ever tried it..??
ReplyDeleteIt's a good book as I heard but I have never tried it
DeleteIs IE irdov enough for olympiads 1st stage
ReplyDeleteit's more than enough even for second stage
DeleteHi aman,
ReplyDeleteI wanted to ask that did ur Physics teacher start any topic from the grass root level or the basic level?
How did he used to begin a chapter and end it?
Usually in the top batches of the coaching institutes the top batch teachers don't begin a chapter from the basics because they think that the kid might have done the basics earlier at home or school. AS most top batch kids are from dummy they have a lot of time to cover the basic part related to the topic but those who go to school may see a clash in the coverage of the topics differently in the coaching institute and school
IN YOUR CASE, u were in the top batch so did see this thing in ur teachers of ignoring the basics.
For some kids this problem of weak basics creates problem for them while they are learning the topics.
CAN U PROVIDE SOME VALUABLE SUGGESTIONS ON THIS ISSUE?
the teacher started from the basics. He assumed that we haven't done anything in advance.
DeleteIf weak basics is a problem, have a look at NCERT before that particular chapter is covered in class

DeleteHey buddy....for theory purposes.....should i follow HC Verma or Resnick-Halliday 'strictly'?I'm a 2015 IIT JEE aspirant.....
ReplyDeleteHi Aman, can u suggest any book on waves(other than HC Verma), i tried Halliday-Resnick-Walker but it seems some important things are missing like wave motion on string,sound waves etc are missing. They are given in Verma though
ReplyDeleteWell you can try DC pandey
Delete(I haven't tried the waves book of DC pandey though)
I guess it must be good because it is meant exclusively for JEE
hii bhaiya....really grateful for ur efforts....

hey aman ,..is TMH of physics a good book.?
ReplyDeleteHi Aman, my name is Siddhant. I am a JEE 2016 Aspirant which means that I m in class 12th right now. My concepts in capacitance are a bit weak which consequently is making RC Circuit and rearrangement of charge part tough for me. Can you please recommend a source that could make my concepts clear? HC Verma is not quite upto the mark. Its too basic.
ReplyDeleteAman please reply ASAP!
ReplyDeleteI want to ask, is NCERT and HC Verma enough for boards along tution notes ?

ReplyDeleteWhat if one wants to get double digit or a single digit rank
What he should do to achieve that....
in cengage and hc verma whoch is better?
ReplyDeletehey bhaiya
ReplyDeletei am in an uttermost confusion.
like you i want to represent India in international,that requires a good understanding of physics
so i am thinking of the order:
resnik /halliday
cengage
irodov
so am i going right?
Hey aman I am a resident of Kanpur too. I joined ashish pankaj and Vivek. My maths and chemistry is good but my physics is of a very low level because Vivek never thought us tough problems now I realized my mistake and going to a good physics teacher .You have written in your blog that you were also weak in physics initially .please tell how to cover up and is it really possible to cover up class 11 physics of her level paralletto class 12th thanks in advance.

ReplyDeleteHello Aman,
ReplyDeleteWhich chapters from I.E.Irodov you recommend for JEE because it is not possible to cover all chapters from this book. Also at what stage we should solve this book..I mean first revise notes, solve workbook from FIITJEE ( I am studying in FIITJEE) then H.C verma and then D.C. Pandy and finally I. E. Irodov?....In short when to and how much to practice from this book and when to practice?
Bhaiya I also have the same problems in mechanics as you had. I wanted to ask you about which version of resnik halliday you preferred- seventh version of resnik halliday walker or indian version by smit gupta?? Please guide me . I am a non attending jee aspirant 2020
