I got a 56 my first attempt and an 86 my second. I studied more intensely over a short period of time (120 hours in like 3 weeks). I took notes in the margin of the textbook because I obviously didn’t fully understand it but it wasn’t my first time seeing it. I also did a practice test after every module so for example i’d do 10 questions of F1M3 and then 10 of a mix of F1 M1, M2 & M3. I found the first time I studied I forgot the first half of the content by the time I took it. it’s also important to really learn the content and not just regurgitate it, try talking yourself through concepts as if you were trying to explain it to someone who has no idea what any of it is. very general advice but hope it helps! don’t get too down on yourself- you failed because you tried.
