Reading:
Yes you will have a good chance with grades like that. I got an offer after interview with ACC predictions from Reading. You could maybe intergate some pharmacy into your PS if you haven't sent it already (but I'm assuming you have as its for medicine....)
You could rewrite one and send it to the uni itself if you want but I don;t see a problem if you just use your medicine PS. Also, have you ever had any experience in Pharmacy?
Interviews will start Nov/Dec I think if its sent already.
