Haha, I completely understand you! You're like, "I'm done with physics after high school," and then boom, college comes and it's everywhere. Particularly in BME (Biomedical Engineering), right? It's like physics is hiding in every nook and cranny, even if you're working with cells or prosthetics instead of rockets. And being the "resident physics person" in your group? Classic move you're like the physics superhero when you're the one who actually understands how things work.
And then AP Physics C was a monster (I recall struggling through that one too). That entire "oh, it's just a B in high school" mentality—then you're working on rotations, oscillations, and lord knows what else in lab, and you're like, this is still most definitely physics. You can't really shake physics once you've had it ingrained into your head, no matter if it doesn't at first glance have to do with your major.
So, so physics tends to hang on you know, even though you tried locking it out back there somewhere. Good job: welcome to the club!
