The post will be useful for the following :
JEE 2015 aspirants (those who are entering class 12th this year)
JEE 2016 aspirants (those who are entering class 11th this year)
How to revise ? One of the most difficult question a JEE aspirant has to face.
How should I revise class 11th syllabus parallel to class 12th ? - I will try to answer this question in this post
Different methods are suitable for different subjects.
Some people would prefer revising from books. Others are comfortable with revision packages.

We will go subject wise :

Revising Maths : Keep solving as many questions as you can. This is the best way to revise maths. It has a number of benefits, most important one being - you won't forget formulas. Additionally, if you are prone to forgetting the formulas, then you should maintain a notebook enlisting all the important formulas in a clear and concise form so that you can go through them quickly in a very short time. Note that you have to prepare the notebook in such a way that you can go through it in a very short time. The reason is that - it's boring to revise the same old formulas if it takes a lot of time. However, if they are written in concise form, then you will be able to revise them more number of times. A better option would be (what I did) to write the formulas in an A4 sheet and carry it with you always. So that you can go through it when ever you have time.
Reading the entire topic again and again from a book would be waste. If you have already covered a topic well, then to revise - the best choice would be to solve problems. For this, you may pick up anything - FIITJEE GMP / TMH / your own coaching material / revision packages. The point is that you should try fresh questions. Also note that you should remember standard questions that have a hidden trick so that you can co-relate it to some other question.
The key to learning maths is solving problems

Revising Physics : I would take up chemistry in the end because it needs more description. Class 11th physics mainly involves mechanics and thermodynamics. The plan would be almost same as that of maths - solve as many problems as possible from the revision packages / books. Additionally, you need to revise the theory portion in physics. For that, I would suggest reading HC Verma. HC Verma is very important from the point of theory. There are small hidden theoretical points that are usually overlooked by students and then these points are asked in More than one correct type questions in JEE. So, it's better to give this book a quick reading over the weekend.
To solve questions, I would prefer revision packages over books because they contain objective type questions that are in accordance to the current JEE pattern. I was from FIITJEE so, I used to solve FIITJEE workbooks, Review package, GMP(I got it from my centre at the end of class 11th itself), and of course HC Verma.

Revising Physical Chemistry : Physical chemistry is more like physics. So the approach would be same as that of physics - read books, solve questions. I would suggest reading NCERT so as to cover all the minute theoretical points that are commonly picked up. Basically NCERT will do the job of HC Verma (for theory). To solve problems, I used same material as given in physics section. Additionally, I solved subjective (solved) examples of RC Mukherjee to develop a deep thinking and a better command over the topic.

Revising Inorganic Chemistry : It is highly likely that you did nothing in inorganic chemistry except chemical bonding. When I say inorganic chemistry, I mean s-block and p-block. Now is the time to do it. You can easily prepare it if you spend just 1 hour a day - 15 minutes revision and 45 minutes mugging new things. Read read and read - nothing more. Inorganic is all about revision and cramming (with sometimes logical thinking as well).

Revision plan :
Now I will be answering the question - "How to balance revision + backlogs + current chapters"
There are 24 ho

Qualitative analysis is viewed as one of the most difficult chapters of inorganic chemistry because it requires sheer cramming with little or rather no logic. This is the perception of most JEE aspirants. But my view is a bit different.
If you study from a good source(which has been mentioned below) then I don't think that this chapter is that difficult as a JEE aspirant feels.
Here are a few tips :
1.) Prepare this chapter by "writing" the reactions on a notebook. You might feel that if you just read it once, then you are done but the case is different. An average JEE aspirant doesn't have that high IQ level. And it has been scientifically proved that we remember things better if we write them once. So carry pen and paper with you when you study this chapter.
2.) A good and reliable study material with a simple language is the best. For example - I used FIITJEE packages parallel to a book called Vogel's qualitative analysis. It's a good book but it is not meant for JEE. You have to study only about 15% of that book for JEE. You might like to try something else. But the above 2 must be sufficient. Note that instead of FIITJEE packages, you might have a different package. But don't worry, all are more or less the same.
3.) Solve a number of problems especially the past year problems. Don't miss a single problem from at least past 25 years. They repeat the questions from this chapter.
4.) In the end, the most important thing is revision. As I have already mentioned in my inorganic chemistry post, all the chapters of inorganic chemistry (qualitative analysis included) require intense revision. You are highly likely to forget everything you did if you do not revise say once a week.

Organic chemistry for me was the most fascinating part of chemistry - most logical and of course, most scoring. If you know that "a nucleophile attacks an electrophile", your half portion of organic chemistry is done (believe me). Entire organic chemistry is dedicated to the above statement.
There are some "Named Reactions" which are very important. I will name some of them - "Reimer Tiemenn" reaction, "Cannizarro" reaction, "Friedel - Craft's" reactions and many others. They all form the backbone of organic chemistry and must be thoroughly covered.
Another important aspect of Organic Chemistry is GOC - General Organic Chemistry. In the recent years, a lot of questions have been asked on - resonance stability, carbocation stability, type of reactions, hyperconjugation and many more topics from this chapter. So it is advisable to cover them well.
For Organic Chemistry, I would suggest a book named "LG Wade" by "Pearson Education". Though the book is not designed for JEE aspirants, it definitely serves the purpose. Do cover the book thoroughly. Practice a lot of questions in order to have a command in Organic Chemistry.
My approach towards learning organic chemistry was "mechanistic". I focused a lot on the reaction mechanisms. In 15 minutes, you can solve entire JEE organic chemistry (if you know the solution). Rather than mugging up organic chemistry, try to understand the mechanism. In JEE, they ask you the entire mechanism of the reaction through Paragraph type questions.

This is a post on Physical chemistry (as demanded by most people).
This branch of chemistry is somewhat similar to Physics and people are fond of it because it involves least mugging out of the 3 branches of JEE chemistry
The chapter on mole concept is most important.
There are other chapters :

Stoichiometry : This was the most difficult chapter for me because I couldn't decipher the secrets of this chapter till the end of my preparation. You are expected to know a number of redox reactions (potassium dichromate , potassium permanganate , sulphur dioxide , hydrogen peroxide etc etc). So you will be comfortable with this chapter only after completing inorganic chemistry. So be patient here.
Equilibrium : Easiest and my favourite. Most logical. Make sure that you are strong not only in numericals but also on theory based problems of this chapter.
Thermodynamics : Difficult one. The material available in market is flooded with second and third law of thermodynamics in detail. But that's something useless. Third law is not in syllabus and second law - only brief discussion + entropy calculation is there in syllabus. Make sure that you are comfortable with thermochemistry.
Chemical Kinetics : again an easy one with very little syllabus
Electro-chemistry : BIG GUN! Just 1 equation - "Nernst's equation" and unlimited applications. If you are not comfortable with any of the above mentioned chapter then this one's gonna be a nightmare
States of matter : simple one but cover liquid states thoroughly(the colligative properties part)
Nuclear Chemistry : easy one. But make sure you know the terms , definitions and properties
Surface Chemistry : is this a part of physical chemistry ?? Most take it as inorganic chemistry. Don't ignore this one or else you are going to regret (for proof check JEE 2012 paper). NCERT is must here.
