Hi there!
I'm currently a third year pharmacy student and it's great to see you applying to Bath. I was in a similar position a few years ago so its completely understandable.
The majority of interview usually take place from late February to April. For me personally, I sent my application quite early (November time) and I didn't hear back until March time for Bath. Some universities interview early and then some take a while so don't worry about it too much! I would say focus on your A-levels and when you get the interview offer, then starting prepping.
In terms of interview, I would say being able to answer the classic "Why pharmacy" question is really important and some basic pharmaceutical calculations would set you up nicely. But as always, don't stress about it too much. 😊
I hope that helps and please ask questions if you have any.
Best of luck everyone!
