There was a google spreadsheet for the FA, and I think the pass rate was around 65-70%. And there were a lot of people who needed repeated attempts, because the FA in general isn’t easy (especially within the 96 hour time limit).
Try to relax and get your mind off of it. Of course it’s easier said than done, but it seems like you did everything you could and it’s out of your control at this point. I used to do the same with exam results, but I later realized that I wasted my time worrying about it during the waiting period (regardless whether I passed or failed).
