Hi, if you start the lecture now, it is manageable. John Moffat’s lectures on F9 are brilliant, I passed that hard paper because of OT and by listening to the revision lectures for past exam papers, how to approach it , techniques, etc.
With F8, it is very much application, so you need to know the techniques on this one on how to approach each question and learn the knowledge bit too. You need to understand the topics more than simply memorising and then applying to the scenario.
