The third edition of CIMA's Official Study Systems are now available to purchase!! With key sections of the 2003 Study Systems being written by the examiners, each text provides a solid foundation and fully reflects what could be tested in the exam.Updated to incorporate legislative and syllabus changes, the third edition Study Systems also address the new and increasingly popular 'objective questioning' exam format, preparing students and helping them to pass the May and November 2003 exams. The revised edition maintains the popular loose-leaf format and will still contain topic summaries and relevant articles. Past papers and solutions including the May 2002 Exam Q&As have also been incorporated.
