The majority of universities that do pharmacy have their entry requirements at AAB-ABB and an A/B in an EPQ will bring down your offer by a single grade generally (not sure about contextual).
To my knowledge the lowest offer you'll get will be BBB and they generally don't do UCAS points. You can get this offer at Reading if you make them your firm and get at least a B in your EPQ.
If you are a first year I would recommend asking your teachers to raise your predicted grades, find out if you're eligible for contextual, go through clearing or take a gap year and apply with your final a level grades. Just remember that your first year grades aren't your real grades and people go up multiple grades all the time especially.
