"Complete Ordinary Level Mathematics Passport " as the name suggests is one of the most recent ordinary level Mathematics books which addresses almost all the requirements of many examination boards at this level across the world. Because the author is a teacher based in Cameroon and has been teaching in secondary schools in Cameroon for more than two decades, special focus has been given to the Cameroon GCE Ordinary level Mathematics 570, the WAEC and the CGSE syllabuses. This 630 pages book covers elaborately almost all the work from form One to Five and more. It is the wish of the author that students from poor countries such as his, should be able to obtain and use just a single book per discipline throughout the secondary school. In these way issues of children failing to do assignments because of lack of textbooks will be illuminated. Concepts, skills, how and why they work are well explained and illustrated. Many recently introduced topics such as logic, networks and flow diagrams have been well treated. An attempt has been made to use mostly real life examples drawn from West and Central Africa especially Cameroon for which the book was originally intended to be used. Names of persons are local names from the English Speaking regions of Cameroon. However, these names do not in anyway distort or change the subject matter. The book contains: Many graded examples and exercises. Many structural and essay type questions for revision and practice. Many multiple choice exercises. A detailed glossary of most of the technical terms used in the book. An index to facilitated quick references of the sub issues discussed in the book. An appendix on the use of the scientific calculator at the secondary school level. Comments on the Book: Highly student centered with a wide range of topics elaborately covered. User friendly with many questions for revision and practice.
