I only hope students are not mislead to taking this subject through seeing labels of philosophy and logic as interesting, some of it seems a pretence, its mostly tedious math based calculations with some theory which could be mathematically construed as philosophical, best advice I can give is, look over the past exams and that will give you the best idea of what this subject is about. That being said you everything apart from the exam is relatively simple (most students attain 45-50% before the exam), the exam then differentiates H1 from~H1 (negation of H1, something which you will become very familiar with ahah).
