Letter to the Candidate Dear Candidate, To pass or not to pass in Agriculture is now your choice. This is because Topmark Revision Agriculture is now available. Topmark Revision Agriculture is a book written by teachers with a wealth of experience in teaching Agriculture in Kenyan secondary schools. In the course of teaching Agriculture in the classroom, the authors have observed that students face enormous challenges. Such challenges include: where to extract material for their examination preparation, what is expected of them in the examination, how to organise their facts, how to manage the allocated time and how to interpret the questions and facts in answering the questions. It is due to these difficulties that Topmark Revision Agriculture was conceived. Content of this book This book contains all the work that is specified in the Revised Agriculture syllabus; for the four-year Secondary Agriculture course
