Preface

“Std. XI: Sci. Triumph Biology” is a complete and thorough guide to prepare students for a competitive
level examination. The book will not only assist students with MCQs of Std. XI, but will also help them to
prepare for AIIMS, AIPMT, CET and various other competitive examinations.
Quick review in the form of charts are provided at the beginning of every chapter. Topic – wise
classification of the MCQ’s has been done to help the students understand each concept thoroughly.
MCQs in each chapter are divided into three sections:
Classical Thinking: consists of straight forward questions including knowledge based questions.

Critical Thinking: consists of questions that require some understanding of the concept.

Competitive Thinking: consists of questions from various competitive examinations like AIIMS, AIPMT,
MH CET, GUJ CET, K CET, EAMCET, BCECE, WBJEEM, CPMT, etc.
Hints have been provided to the MCQs which are broken down to the simplest form possible.
An Evaluation Test has been provided at the end of each chapter to assess the level of preparation of the
student at a competitive level.
An additional feature of pictorial representation of a topic is added to give the student a glimpse of
various interesting biological concept.
The journey to create a complete book is strewn with triumphs, failures and near misses. If you think we’ve
nearly missed something or want to applaud us for our triumphs, we’d love to hear from you.

Best of luck to all the aspirants!

Yours faithfully
