Most uni's say you don't HAVE to have experience in an actual pharmacy as long as you have experience in a care home or something but personally I think you really should. There are pharmacies absolutely everywhere so unless you live in the middle of the countryside I can't imagine it'd be too hard to get a place, even if you just go for a few days. You can't dedicate yourself to wasting your ucas choices and paying a huge amount of money and spending so long studying Pharmacy if you've not even experienced it, especially with it being so much harder to get a job now, and honestly I think I'd of really struggled to do a decent personal statement and answer my interview questions well if I hadn't of done any work experience
Assuming you're at school, you've got the whole of summer to get yourself sorted. Try get a placement and then make note of everything you learned whilst it's still fresh in your head so you can use it in your PS and interviews. Even if you don't get anything over summer, there's always the october holidays, you don't have to send it off ASAP, getting experience is much more important than rushing to send it off
