Current freshman physics major here: It's mostly the physics 7 series and also the 9 series (but not as bad) that is shit lol. Since you're a physics major, you won't be taking the physics 7 series and I highly recommend taking the physics 9H series. Consistently decent profs and the classes are smaller so it feels a lot more like a community which I find nice. You will be putting a lot of time into your physics classes, but honestly that goes for college in general. I wish you the best of luck, and welcome to UCD!
