The book intended exclusively for the usage of students, teachers and persons who are related to competitive exams. The book is based on our experience over the past 8 years and design on the basis of current competitive level of Engineering like IIT JEE mains/ Advanced, MHT-CET, BITSAT + NTSE, KVPY, Olympiad, IIT Foundation + CAT and other state engineering exams in India, where 1194938 i.e. around 12 Lakh of students (Year 2016) write a single engineering exam. As an educator, I understand the student’s need of these topics and the difficulties faces by students in transition from standard 10th to 11th class. As students enter their 11th standard, they find a substantial change in the course content and level of difficulty. They find some totally new concepts of Mathematics, widely used in Physics and Chemistry. They may be completely unfamiliar with concepts of absolute value, Interval Methods, Set Notation, inequalities etc.

 The book has been prepared for them to learn the concepts of algebra from basic to advanced level of thinking. The book is prepared to serve as a bridge for 10th to 11th standards, CAT aspirants etc. Software engineers can also be in benefit in writing the code due to concepts clarity.   

 The book contains the following Learning Methodology. 

 (i) Basic concepts and easy learning.

 (ii) Necessary examples and experiments for beginners level to expert.

 (iii) Psychology of student’s brain and their thinking.

 (iv) Pictorial view of problems and solutions.

 (v) Challenging problems (Ultimate Finish – for Top All India Rankers between 1 - 500).

 (vi) Exercises and Assignments to test the understanding and growing knowledge.

 (vii) Sample Test Paper to have experience before actual exam.
