This text has been specifically designed to prepare people with previously limited chemical knowledge for entrance into science-related courses which involve chemistry in higher education. It effectively forms a self-study course, which is split into separate modules and units covering the spread of concepts required for those needing a basic knowledge of chemistry. The material is presented in an easy-to-use manner which allows the student to pace their acquisition of knowledge and gain increasing confidence in order to succeed in understanding essential relevant concepts. Other features of this book include starter diagnostic tests, worked examples and self-study tests at the end of each chapter.
