Of course it is examinable – it is a very important part of the syllabus!! Everything in our free lectures is relevant for the exams.
I have no idea what will be examined. Overall everything will be examined, and all the examiner tells us is that Section C will mainly be from the investment appraisal, business finance, and working capital areas of the syllabus (but, of course, anything in the syllabus can appear as parts of questions).
