Want to drop biology and swap it for something else

I am doing 3 a levels. Biology, textiles and psychology.
Ever since we had to pick choices for college I have changed my choices like 6 times. I am still not happy with my choices now. I am doing really badly in Biology and psychology and only barely okay in textiles. I want to drop Biology since I am doing really badly and I don't really enjoy it.
I have thought of dropping psychology but I think I can stick at it. Though it can be boring, I still find myself wanting to revise psychology over Biology and my grades are a little better though overall probably not by a lot. Plus dropping two subjects might be too much.
I have ended up deciding on radiography as the subject I want to do in uni if I don't have something I am passionate about. There are two unis nearby and for radiography one accepts one science subject including Biology and psychology and there other wants two and they can be biology and psychology. They both accept applied science which I am thinking of switching to. I am not sure if I can though since it is coursework based.
The other thing I am interested in is Media studies but that is also coursework based and even if I can do it I will be limited to one uni in my city. It might be important to add that I would prefer to do a radiography degree apprenticeship instead of go to uni if there is that option which I think will require 2 sciences but also from my research it is very hard to come by.
Overall, I am just so fed up with college and a levels and don't know what to do. Any advice?

maybe go for maths if you were to drop it
maths is a subject that can open up a lot of career paths
but i would think a lot about actually dropping a subject as its not a small thing

You may be better of just to stivi it out as y13 goes by quite quick
