This book is written with the intention to distinguish itself from other self-help books by: 1) Attempt to provide more comprehensive explanation behind concepts, so that students are able to grasp with better understanding for each section. 2) Provide examination focused tips to aid students to streamline importance during revision. 3) Content is organised in such a way that only focus on important examination concepts to be tested, as well as application concepts linking to other topics. Given the varying content taught to students across Singapore for Chemistry, the author hopes that this guidebook can help to standardise the content taught, so that each student is able to have a common understanding of what will be tested and avoid unnecessary content that may impede their learning progress.
