comprehension of fundamental principles of physics for medical aspirants The content of the book is also beneficial for preparation of AIIMS, JIPMER and other state-level medical entrance examinations The author has strictly adhered to the latest pattern of NEET and developed the content in line with previous years’ papers from AIPMT/PMT/NEET and other competitive medical entrance examinations of last 15 years All chapters in this book conform to the pattern laid out in NCERT textbooks Each chapter starts with key concepts followed by a large number of practice MCQs Questions from previous years’ AIPMT and AIIMS examinations with important solutions have also been included In addition, there is a separate section on AIIMS Essentials designed to prepare students to answer the “Assertion and Reason” type of questions A separate section on AIIMS previous years’ questions is also provided This book is written in an easy-to-understand language, with illustrations, tables, and highlighted text-boxes for last minute revision I hope this book will standout as a trusted solution for any physics-related requirement of medical aspirants and assist them to succeed in the examination Features: ❒❒ Structured as per class XI and XII syllabus of NCERT ❒❒ Chapter-wise NCERT exemplar questions ❒❒ Assertion and Reason questions to aid in preparing for AIIMS and other similar examinations ❒❒ Previous years’ questions embedded in every chapter ❒❒ Mock tests and sample papers for practice ❒❒ Solutions for the latest NEET question paper I have ensured to make it an error free resource with the best assemblage of concepts and questions Despite our best efforts, some errors may have inadvertently crept into the book Constructive comments and suggestions to further improve the book are welcome and shall be acknowledged gratefully You may contact us at reachus@pearson.com Acknowledgements I express my deepest gratitude to my teachers and parents, without their support this book would not have been completed I am also grateful to my wife, Awani; and my little daughter, Meethee I would also like to thank to all of them who provided me invaluable support in presenting this book I extend my sincere thanks to the editorial team of Pearson Education for their constant support and sincere suggestions Abhay Kumar FM.indd 11 8/3/2017 10:34:20 AM About the Examination National Eligibility Cum Entrance Test (NEET) is conducted by the Central Board of Secondary Education (CBSE) for the 15% ‘All India Quota’ seats in the Medical and Dental Colleges in India The merit list of this entrance test is also used by state governments/universities/institutions for admission in the medical/dental colleges against seats under their control Time Management In order to successfully crack NEET, one must prepare profoundly Consistent hard work, practice and perseverance are needed to crack this examination Statistically, NEET is one of the toughest examinations in India During this examination, one must exercise clinical precision with speed since the average duration to respond to one question is hardly a minute The aspirants should be conceptually clear in the subject owing to the negative marking in the examination A better strategy to solve the paper is to go for the easiest first and then the toughest questions Regular practice of MCQs will assist the aspirants to assess their preparation for the examination In a nutshell, hard work, conceptual clarity and self-assessment are the essential ingredients to achieve success in NEET NCERT texts play an important role in understanding the concepts All concepts/theories must be referred in a regular manner NEET is hour examination, with total 180 Multiple Choice Question (MCQ) to be answered The exam paper will be divided into four sections—Physics, Chemistry, Zoology and Botany Each question carrier marks Time Management Tips Step 1: First 30 mins: In order to solve maximum questions in limited time frame, attempt the easy questions first You may start from Physics/Chemistry Section, where some problems may be answered by comparing the units of the options Step 2: Next 60 mins: Attempt Section II or III For few questions, where dimensional analysis fails, recognize the proper limits of the answer and mark the correct answers Step 3: Next 60 mins: In some problems, solution may not be obtained from a simple formula and hence we need to calculate the formula At that time try cause and result method to solve the problem and use estimation rule Step 4: Last 30 mins: Try the difficult questions of Physics and Chemistry and revise the complete answer script FM.indd 12 7/28/2017 5:27:13 PM Trend Analysis 2007-2017 Number of Question(s) in Ch No Chapter Name 2010 2010 2011
