Welcome to London Revision International. LONDON REVISION: EDEXCEL IGCSE 2009-2011 LONDON REVISION materials are all written by senior examiners and can be duplicated, amended and photocopied copyright free in purchasing institutions. If you are finding the cost of resourcing the new specifications too high, our E-Books are the answer. You simply buy the sections that you require and make them available to students via an intranet. Sets of textbooks can usually only be used in class, but E-Books are available to all students at any time and allow the use of two detailed texts at the same time. All students can now have access to comprehensive textbooks at home, which makes setting homework much easier and saves on photocopying. If students do not have access to the network at home, E-Books can be photo-copied and duplicated within the purchasing institution or saved on a CD-R and given to students. What could be simpler, OR cheaper! E-Books (E-B) contain detailed content and exercises for students to complete; they can be used in class or to set homework. Each Study Guide follows the exact demands of the specification. They contain detailed text covering key content, exercises, sources, visuals and hyperlinks to further materials such as on-line exercises, photographs, power-point presentations, biographies, sets of photographs and posters and film. They are ideal for students studying independently. E-Books will cover all areas of the specification; we have published chapters for all of the units in each of the modules. Unlike other publishers, we sell each chapter or unit separately; you just buy the chapters that you need for your options. AND, you need only buy one copy and duplicate it as many times as you like within your school. Student Workbooks (SWB) cover basic content; they are suitable for students working towards a Grade C Revision Notes (RN) are in bullet point form around key questions and follow the exact demands of the specification. Notes will cover the complete specification. Revision Tests are objective tests covering content; each has twenty questions along with answers. They will cover the entire specification.
