The monograph "Explicit Chemistry: A Revision Course" for WAEC, NECO, UTME, POST-UTME and other related examinations written by O.J. Olaoye is a complementary text to the various textbooks that have been written in the subject area. This book has become timely in view of the poor results that are being witnessed in the UTME examination especially in the sciences and mathematics, biology inclusive. These majorly are due to poor or inadequate access to good study materials. Each chapter has annotated topics followed by copious specimen questions on some past UTME and POST -UTME examination, for practice and emphasis. The topics in each chapter are adequately treated and with clarity. The illustrations are simple but effective. The author has done a lot of work and put in efforts to come out with a very readable and useful text. It is highly recommended to all the students aspiring to undertake WAEC, NECO, UTME and POST-UTME examination, in order to improve highly their chances of success
