Hello OhNuts,
I felt similar to you this time last year. Though my initial dilemma was whether to look into taking Medicine or Pharmacy.
Because I wasn't sure of which to do at the time, I went for an access course, in order to keep my options open, but just before the start of the access course, I decided to focus on Pharmacy.
Like you I have no A-Levels and was hoping to just use the access course as a route onto the MPharm degree at university.
One year on, I've nearly finished the access course, I supplemented it with a few additional qualifications (Maths GCSE and IELTS exam), and now I have 3 offers, 1 rejection and 1 university application still pending. At this point in time I'd say I know for sure that the majority of those still on my access course (a couple of people dropped out) have an offer from a university. The rest, I'm not sure if they have offers yet or not.
So based on my experience doing an Access course, I can confidently say you have a chance of getting onto the MPharm degree at University. Though be warned, not all access courses are the same, and not all the Universities offering MPharm accept access courses. And like you mentioned, all of us that have offers all went to interviews and aimed for minimum distinctions throughout the course. Though of course, this year (2011) is apparently a highly competitive year due to supposed funding cuts, reduction of places and tuition fees rising next year. Though apparently what we've gone through is not that different to the previous students on our access course. However, I don't know how similar or different things will be for 2012 entry.
If you have any questions,feel free to ask.
