The SPM Physics Workbook is developed under the One-School.net Free Books Project. The content of this book is strictly follow Malaysia SPM (Sijil Pelajaran Malaysia) syllabus. The aim of this project is to provide a complete electronic supplementary network for students to develop self-learning skills by breaking the spoon-feed rituals and to encourage them to compile educational information from the Internet.
