My students and I reviewed and selected this book for our revision text. The students use the book for the whole of year 12 as a supplementary text to the one the school assigns. They like the clear explanation of the material. There are excellent revision tools, helpful writing techniques and a bank of HSC style questions to practice with. All my students will be working through their summer holidays with this book to be ready for the in class assessments for the first three terms of next year. If a student is highly motivated they could work through it by themselves but some guidance from an experienced learner is always helpful. Worth every penny.
