To become a Nurse/ODP with an NVQ Level 3?

Hello everyone,
I'm in need of a bit of advice. If anyone can help me? I've worked in the NHS for a number of years now, in the last year in HCA capacity. I enjoy the role and love the interaction and general care i provide for patients. I do find though, the limitations of my job role severely frustrating. I aspire for progression, I have applied to study for my NVQ 3 qualification as well as brushing up my Maths & English at level 2. Which is a good start, I'm interested in becoming an ODP and was wondering if anyone knew if i could successfully apply for the Diploma (in the aforementioned) with this qualification? I am also interested in doing my training but the Adult Nursing Diploma isn't an option in the 2012 university prospectus. I am aware of an Access to uni course(s) that are available. But to financial commitments I am unable to attend college full time. Due to unfortunate circumstances i wasn't able to obtain my predicted GCSE results, which were taken over 11 years ago. Could I find a placement on a degree course with a nvq 3 and level 2 maths and English?

Any feedback would be greatly appreciated
