This book on mnemonics has been writen in view of problems
faced by PG aspirants and MBBS students. All the hard
work comes to naught if a student confuses while giving
examination. Mnemonics has been prepared to eliminate the
confusion one encounters during memorizing the points in a
topic. This book is sure to improve your rank in any PG
entrance examination especially the one based on factual
questions like DNB and state PG entrance examinations. Only
600 mnemonics has been included in this edition to enable
students to complete and revise the book in a short time.
Students are also encouraged to point out the mistakes in
this book for which they will be given the incentive of ` 50/-
recharge done in their mobile number provided they are the
first to point out the mistake and give reference for the same.
One lucky student will also get to avail free discussion and
explanation with the author every week. For this they need to
provide their name, college name, batch of MBBS admission to
author’s contact number.
Readers are also advised to give their valuable opinions and
suggestions which will be appreciated and acknowledged.
