definitely don’t drop out. I don’t know about Oxford, but at Cambridge, once you’re in you can change courses relatively easily.
Also, as the first person said — it’s a super strange first year rn and won’t be representative of normal teaching & learning. If you’re quite unhappy though, talk to your tutor (I don’t know what the welfare/personal tutor person would be called at Oxford, but that person) about changing courses before you even begin to consider dropping out. You got this!
