The topics of relevant and irrelevant costs were tackled in the 2014 specimen exam but arent discussed in the f2 videos (from what I remember). Is this because it was from an old syllabus and therefore is not needed anymore for 2020 exams or do we still need to learn that?
Relevant costs are only relevant in the Paper MA exam in the context of discount cash flow, and are dealt with in the lectures on discounted cash flow.
