Ib sl physics or sl bio??

Hi, I’m just starting DP1 and am in the first two weeks, where we’re allowed to change our subjects. I initially chose biology, though I took both in IGCSE and scored high A’s.
Biology seems to be alot of memorization, which I dislike (my other HLs are math aa, psychology and Economics). I’m not super passionate about the content itself, but I’ve heard it’s easier to grind in and get a 7, which could benefit the overall ib score? I do enjoy bio, but not that much and I find it a bit tedious.

Physics I had to dedicate more time in to understand during IGCSE, but I’ve always been more passionate about- I feel like I prefer less but harder content, which I also find interesting, and I would be willing to work hard in physics, but want to have time for my other HLs especially math. I heard the physics sl papers are also pretty tricky.
In university I’m mainly planning to study the social sciences (psych or econ), if that’s worth nothing.

Do any DP2 students, graduates or others have any advice on what to do? Thank you!
