Book excerpt: The General Science section covering Physics, Chemistry, Biology and Computer Science has taken an important dimension in most of the competitive examinations like SSC, CDS, NDA, Assistant Commandant, CPO, UPSC and State Level PSC Exams and those lacking the basic General Science knowledge lag behind others in the long run. The present book will act as an Objective Question Bank for General Science. The book has been prepared keeping in mind the importance of the subject. This book has been divided into four sections namely Physics, Chemistry, Biology and Computer Science, each divided into number of chapters as per the syllabi of General Science section asked in various competitive exams. The Physics section covers Motion, Force & Laws of Motion, Gravitation, Work, Energy & Power, Simple Harmonic Motion, Wave Motion, Light-Ray Optics, Current Electricity & Its Effects, Nuclear Physics, Semiconductor, Communication, etc whereas the Chemistry section has been divided into Atomic Structure, Chemical Reactions, Chemical Bonding, Solutions & Colloids, Energetics & Kinetics, Electrochemistry, Metallurgy, Metals & Their Compounds, Flame & Fuel, Food Chemistry, etc. The Biology section in the book covers Biology & Its Branches, Cell: Structure & Functions, Cell Cycle & Cell Division, Plant Tissues, Animal Nutrition, Plant System, Reproduction in Organisms, Respiratory System, Excretory System, Reproductive System, Genetics, Biotechnology, Animal Husbandry, etc whereas the Computer Awareness section has been divided into Computer Organisation & Memory, Data Representation, Software, Data Communication Networking and Internet & Computer Security. The chapters in the book contain more than 100 tables which will help in better summarization of the important information. Each chapter in the book contains ample number of objective questions ample number of objective questions including questions asked in previous years’ exams which have been designed on the lines of questions asked in various competitive examinations. With a collection of more than 5000 highly useful questions, the content covered in the book tries to simplify the complexities of some of the topics so that non-science students feel no difficulty while studying general science. Also hints and solutions to the difficult questions have been provided in the book. As the book thoroughly covers the General Science section asked in a number of competitive examinations, it for sure will work as a preparation booster for various competitive examinations like UPSC & State Level PSCs Examinations, SSC, CDS, NDA, CISF and other general competitive & recruitment examinations.
