It is our intention to compile this series of learning aids – to help Form 1 to From 3 students to grasp the vocabulary, fundamental knowledge, and the basic concepts of general science systematically and logically. We have prepared many challenging questions and have given students plenty of chance to think and to design experiments. There are many STSE (science-technology-society-environment) related topics, so that when students are learning science, they are at the same time keeping themselves more and more familiar with the science-related issues in the society and in the environment. When they encounter problems, they would be more ready to solve with ease and confidence.

Our books are some learning aids, very useful and helpful for preparation of examinations, but totally different from other similar texts, we the authors write our books with passion, faith and mission. Throughout the essential notes, questions, and exercises there is our love for our young generation, our concern for the nature and sustainable development, and our sincerest hope that we are able to help our students learn science by inquiry and investigations.
