Typically, the SBL are devised about one year in advance so they will not reflect current events. Furthermore, the examiner says that all questions are self-contained and you do not need to bring in real-life events such as oil or gas price rises.
Identifying key topics is rather like providing tips – which we don’t do. Just practi e recent questions and look at the notes and technical articles if you need more information about a topic.
Approach questions firstly by taking a common sense approach then see what models etc will help your answer.
