I am not a pharmacy student yet but do know a lot about the profession and and what it is like at uni, there is quite a lot of chemistry involved, this is the main science you will be studying at uni, you can go into specialities after your training year and a few years on the job, I would say if this isn’t your main passion then it might be best to not go for it as it is one of them jobs i personally feel where you have to be able to enjoy to actually do well (but again that is my personal opinion others might not agree)
You can find lots of information online about different specialities, career paths, key topics at uni, so it’s definitely worth looking into if this is something you are possibly considering
