Are you sure you want to do pharmacy and have done in depth research about the course and the career? Make sure you love it. It will definitely include a lot of chemistry, so it’s imperative that you find that interesting. If so, I think you can withdraw any applications that you haven’t heard back from yet and use those to apply elsewhere. If you’ve heard back from them all/ used all 5 options, they you may need to apply for next years admissions. However, I’m not entirely sure - as there may be clearing, etc.
