Are my GCSEs good enough for med

I wanna do med at a Russel group preferably in the UK. I have looked allot online and ik that gcse requirements aren't extremely high for certain unis and that their min acceptance is grade 6 with a preference for 7-9.

However, med is super competitive. I did maths eng lang eng lit triple science and Arabic.
My chem was a 6 and my arabic was a 9. The rest are all 7s.

Does anyone know from experience anyone who has similar gcses to me who's doing med in a Russel group? Do I need to Retake chem gcse? Can I make up for it by excelling in the rest of my med application? Websites aren't making it entirely clear to me.
