Hey there! We are MBBS undergraduates from AIIMS Delhi. We are part of a team called ‘Aim4AIIMS’ which tries to help students, try to realise that cracking the AIIIMS exam is no enigma. The main idea behind the blog, guidance program and this study material was that students or rather aspirants were quite confused about what to study and what not to. Coaching institutions and competition books dump a lot of information to claim that answers to questions appearing in examinations could be found in their material. This material of AIIMS series is no such attempt and should not be considered as an absolute one. Most of the writing is a conservation sort, more on the informal side - may help you not put off with physics. This book has been written to help student to supplement their preparation in physics.
