Tips for Cambridge Medicine as a Year 10 (PLS HELP)

Hi I'm in Year 10 currently at a highly competitive grammar school in Sutton.
For my predicted grades for this term I got mainly 8s, a few 9s and two 7s. I really really want to go to Cambridge or Oxford to study medicine. It has been my dream since Year 4. I know both are really hard to get into but that Cambridge is slightly easier. However I notice that many colleges need subjects from bio,chem,maths,physics or further maths. so its either i do bio,chem,maths or bio,chem physics and i hate both physics and maths. what should i do?
and also, the colleges for cambridge i want to apply to are trinity, corpus christi, christs and kings which are very competitive. is there anything i can do from now to really boost my applications???
plsss do add any other random advice i rlly need it

For Cambridge Medicine Maths is must and you must love it. You may already know that once you graduate as a MBBS Doctor. No one cares if you had graduated from Cambridge or Oxford and there is no incentive other than self-satisfaction. All the best

oh ok thank you. so does that mean if i choose bio,chem,physics i wldnt get offered a place?
