PREFACE
It is a fact that nearly 10 lacs students would be in the race with you in JEE Main, the gateway
to some of the prestigious engineering and technology institutions in the country, requires
that you take it seriously and head-on. A slight underestimation or wrong guidance will ruin
all your prospects. You have to earmark the topics in the syllabus and have to master them in
concept-driven-problem-solving ways, considering the thrust of the questions being asked in
JEE Main.
The book 40 Days JEE Main Chemistry serves the above cited purpose in perfect manner. At
whatever level of preparation you are before the exam, this book gives you an accelerated way
to master the whole JEE Main Physics Syllabus. It has been conceived keeping in mind the
latest trend of questions, and the level of different types of students.
The whole syllabus of Physics has been divided into day-wise-learning modules with clear
groundings into concepts and sufficient practice with solved and unsolved questions on that
day. After every few days you get a Unit Test based upon the topics covered before that day.
On last three days you get three full-length Mock Tests, making you ready to face the test. It is
not necessary that you start working with this book in 40 days just before the exam. You may
start and finish your preparation of JEE Main much in advance before the exam date. This will
only keep you in good frame of mind and relaxed, vital for success at this level.
Salient Features
Ÿ Concepts discussed clearly and directly without being superfluous. Only the required
material for JEE Main being described comprehensively to keep the students focussed.
Ÿ Exercises for each day give you the collection of only the Best Questions of the concept,
giving you the perfect practice in less time.
Ÿ Each day has two Exercises; Foundation Questions Exercise having Topically Arranged
Questions & Progressive Question Exercise having higher Difficulty Level Questions.
Ÿ All types of Objective Questions included in Daily Exercises (Single Option Correct,
Assertion & Reason, etc).
Ÿ Along with Daywise Exercises, there above also the Unit Tests & Full Length Mock Tests.
Ÿ At the end, there are all Online Solved Papers of JEE Main 2019; January & April attempts.
We are sure that 40 Days Physics for JEE Main will give you a fast way to prepare for Physics
without any other support or guidance.
