MPharm without biology or maths?

so im doing alevel chem phys and politics (weird combo and i totally regret dropping and switching out my original bio and maths. but im going into yr 13 so its too late...) and i know some universities will accept as long as i have chem, but i really would like to get into the university of manchester, but it says i need AAB including chemistry and either maths or bio, even with foundation year.
so i was wondering if theres a chance or if i should just go to other unis?
any answer is appreciated, thank you
