I think study past exam papers is very important. If you have enough time, practice an exam paper like you were actually sitting in the exam.
summarise those models (AAA, Tucker’s, Mendelow,etc), stages (for example, process of risk management), important definitons, summarise format of letter, memo, email, article, report to get the profesional mark, study the advantanges, disadvantages, roles of different individuals (ED,NED,stakeholder, institutional investors) and committes (risk committe, audit commiitte)
thats what im doing for this exam, hope it’s helpful
