JEE Main

Getting a rank under 100 in IIT-JEE is a pretty hard nut to crack. Not everyone can achieve this, but if you are determined then we all know everything can be achieved. For this, you will have to study every single day. Not just study, but study in a good way or we can say you will have to do smart work not hard work.
Here are few books to score good marks in JEE Mains:
Physics:
1. Concept of Physics (Both Part 1 & 2) by HC Verma
2. Problems in General Physics by I.E. Irodov. This book is really very good. You can solve this book after solving topics from HC Verma.
3. Aptitude Test Problems in General Physics by Krotov, but go through this book only when you are very good. Otherwise, this book may hamper your preparation.
4. Understanding Physics by DC Pandey.
This is quite a good book to score good marks as it has competition corner in which questions are quite good.
Chemistry:
R.C. Mukherjee for Physical Chemistry problem
Morrison and Boyd for Organic chemistry
Solomon's and Fryhle for Organic chemistry
J.D. Lee for Inorganic Chemistry
O.P. Tondon for Physical Chemistry
Mathematics
TMH old edition book (2003 or earlier). This is one of the best books, but you should take only old edition, I am not talking about new edition(s).
Cengage books. This is also good and questions are also good.
One must go with the best coaching module such as Resonance, FIITJEE or Allen and must solve the past 37 years JEE problems.
All the best.

Hello Dhruv,
There are two parts namely JEE Mains and JEE Advanced.
In mains, the questions are not that tough, but they require high conceptual knowledge and solving skills.
The questions are from PCM only based on classes 11&12 syllabi (NCERT).
First, you can go through the concepts in PCM as they play a major role in any of the exams.
The questions in JEE Mains will be generally easy, but you need to master the concepts to be fast in answering as the time is not more.
You can prefer NCERT books for getting conceptual clarity. Then you can prefer TMH (Tata Mc graw hill) and Arihant books for PCM concepts as well as problems.
They are really good books for JEE preparation and they provide good quality of exercises for practice.
You can solve as many problems as you can within time limit so that they will provide you a better way of preparation for JEE Mains.
The previous year papers would help you a lot to understand the quality of questions in JEE.
At the last days of preparation, it is good to avoid new topics and give as many mock tests as possible.
Stay focused and work hard.

If you are preparing it for last two years, one year or 6 months or even you have studied well for boards then you have a chance to get a place among the toppers by following few tips mentioned below.
These tips consist of the outcomes of the students who commit the major mistakes in the exams and perform well in their tests.
Number one, don't try to revise the whole chapter as it will simply consume your time and you will be left with nothing at the end.
Focus more on concepts rather than books and practise sheets quantity.
Be confident about your preparations and don't get demotivated as someone in your institute will pretend to be intelligent but believe in yourself.
Practising the previous year's questions is the mandatory part.
If you want to get all the fundamental and theory knowledge, you can prepare and practise questions from the questions asked in 2005.
At last, take a healthy diet, don't expose yourself much to the outer world till the exams and try to remain safe if possible at the home because our one mistake can ruin our hard work.
Thank you and best of luck.

It differs from person to person depending on one's current academic performance. But yeah it sure is possible to crack IIT JEE Mains and Advance in 1 year if you follow the proper routine. Some of the tips are mentioned below:
- From the point of view of a proper routine, the minimum time you should be dedicating is at least 5-6 hours on self-study regularly. You should split the self-study time into two core parts: one for revision purpose and second for day-to-day self-study. Revision is very essential because syllabus of class 11th and 12th PCM is vast.
- Join a coaching institute and resolve their study materials repeatedly. Nowadays there are numerous tablet courses existing such as Aakash and Plancess. The advantage of joining tablet courses is that you have plenty amount of time for self-study which I contemplate is most vital piece when preparing for IIT JEE. You can go for classroom courses also but yeah then your timetable will be a bit tiresome. But it depends on you if you can accomplish 6 hours of self-study after attending classes or not. Also, they have introduced Adaptive Learning in their test series which I think no other institutes has done yet. -Watch sample lectures yourself in YouTube and go for the one that suits your need well.
- You have to put equal importance to all the three subjects. If you neglect any of the subjects then you will never be able to get rank below 1000. In fact, it will even decrease your probability of clear IIT Advance significantly.
- Always take part in All India Test Series. In this matter, Aakash is best as many students participate in Aakash All India Test Series. FIT JEE also good when it comes All India Test Series. All India Test Series will give a proper assessment of where you lie among the crowd as you will be competing with 12 lac students in IIT JEE Mains. So, you should have an idea about what it is like to compete with students from different parts of the country.
