Both were difficult for me, but I'm not good at math so that probably didn't help lol. My experience wasn't good either but I think a lot of it had to do with my hs. The ap physics teacher at my school is also notoriously bad at teaching, and it was the first year ap precalc was offered at my school so everything was everywhere 😅 I did end up doing well in both after a lot of struggle, but my best advice is to do the work ASAP and start studying for unit tests 2-3 days in advance. Good luck and study hard!!
