I would say that for many course where there is not intense competition resits will be fine. You should be able to do a bit of research to find out. I would suggest not to give up on the physics completely, you can deprioritise the time allocation and still achieve a pass which is still an achievement to be proud of and might be enough to do what you want. I got B, B, E minimising the time I spent on my weakest subject. The E was just as useful in getting a uni place though.
