Access course or foundation year ofr pharmacy

Could someone please help me? I've started an Access to Science course, and it's going okay so far. However, I need to achieve all distinctions to qualify for Pharmacy. I'm currently debating whether I should switch to a foundation year for bio pharmaceuticals science , where I would need to get 70% to apply for Pharmacy through UCAS. I'm really unsure about which path is the right one to take, and I still have time to make the change before it's too late. This decision is really stressing me out, and I don't know what to do. Any advice would be appreciated.
