The only way to study is to work through any textbooks that you have, work through our course notes (and watch the lectures) but most importantly to practice as many questions as possible. Best is to get a Revision/Exam Kit from one of the publishers, but at the very least download all the pas exam questions from the ACCA website. Also, the more general background reading you do the better (with regard to general economic factors in the world) – read the business pages of a decent newspaper regularly.
