Just the facts, ma’am. That’s about what you get with this series. Each book begins with an assessment test so that you can gauge a student’s understanding; this allows you to spend time and effort only where necessary. The bulk of the book is devoted to short practice exercises, which are preceded by simple explanations of concepts. A final assessment test shows how much the student has learned. Answer key is included in the back of the book. An excellent choice for remedial or brush-up work as needed. Approx. 35 pgs.
