Is this enough for medicine or should I retake?

I did my gcses and I would say they're pretty average. I got ...
English language - A
maths - C
biology- A
chemistry- B
physics- B
History- A
Geography- A
Spanish - A

I want to retake the ones I didn't get an A in but I don't know if unis will look down on them.

I currently take biology, chemistry, English lit and history.
