PREFACE
To get admission in a premier institute of technology is the dream of each student opting for science.
Admission in these institutes is based on clearing with a good rank in the All India Engineering Entrance
Examination.
To score a good rank, aspirants have to answer questions ranging in difficulty levels in the shortest
possible time. Therefore, one has to learn techniques to solve these questions. This has been kept in
mind while presenting this book so that a candidate should master the art of solving at the fastest rate
such that almost all problems are solved with accuracy.
The unique features of this book are:
• Definitions, concepts, formulae, etc. form the brief review about each topic.
• Shortcuts and points to note provide ready-to-use formulae and other shortest possible
techniques to solve the problems.
• Caution helps students avoid committing common mistakes.
• Self tests and questions from competitive examinations with answers and explanations are given
at the end of each section.
• Model test papers with their explanations are given at the end of the book.
The ideal method to prepare for the examination is as follows:
Read the Brief Review, Short cuts,
Caution and Solved Problems of the
chapters thoroughly
Solve the Problems for Practice with
a clock before you.
No
Yes
Read again the Brief
Review, Short cuts, Have you
Caution and Solved solved 60 questions Go to
Problems. Note down correctly in 40 minutes? next chapter
what you have not
grasped.
Adoption of the technique in the flow chart ensures 100 per cent success. Work hard, hard work is
the key to success.
With best wishes for a great future.
