The pathway to success
About this book
This book has been written primarily as a revision course for students studying for the
CSEC· Chemistry examination. The facts are presented concisely using a variety of
fo rmats which makes them easy to understand and learn. Key words are highlighted
in bold type and important definitions which must be learnt are written in italics
and highlighted in colour. Annotated diagrams and tables have been used wherever
possible and worked examples have been included where appropriate. Questions
to help test knowledge and understanding, and provide practice for the actual
examination, are included throughout the book.
Th e following sections provide valuable information on the format of the CSEC·
examination, how to revise successfully, successful examination technique, key terms
used on examination papers and School-Based Assessment.
The CSEC® Chemistry syllabus and this book
The CSEC· Chemistry syllabus is available online at http://cxc-store.com. You are
strongly advised to read through this syllabus carefully since it provides detailed
information on the specific objectives of each topic of the course, School-Based
Assessment (SBA) and the format of the CSEC· Examination. Each chapter in this book
covers a particular topic in the syllabus.
• Chapters 1 to 13 cover topics in Section A, Principles of Chemistry
• Chapters 14 to 17 cover topics in Section B, Organic Chemistry
• Chapters 18 to 24 cover topics in Section C, Inorganic Chemistry
At the end of each chapter, or section within a chapter, you will find a selection of
revision questions. These questions test your knowledge and understanding of the topic
covered in the chapter or section. At the end Chapters 13, 17 and 24 you will find a
selection of exam-style questions which also test how you apply the knowledge you
have gained and help prepare you to answer the different styles of questions that
you will encounter in your CSEC· examination. You will find the answers to all these
questions online at www.collins.co.uk/caribbeanschools.
The format of the CSEC® Chemistry examination
The examination consists of two papers and your performance is evaluated using the
following three profiles:
• Knowledge and comprehension
• Use of knowledge
• Experimental skills
