Grrrr just replied and pressed the wrong button...
In short, we were told there were about 800 people who applied for 69 places in my cohort, and the training places have gone down in the years since (55 for 2011 start). If the only reason you are ditching nursing is because it is hard to get into, you might want to think long and hard about choosing physio as an easy option. Graduate opportunities are also pretty few and far between in the NHS, and I would certainly say as a qualified nurse you will have more jobs open to you. Furthermore, you will need to demonstrate a desire to study the course meaning you will need work experience prior to interview. This is maybe where I would start if I were you - a physio degree is full on, and if you spent three years going through the motions, I don't think you would survive. As for London unis - off the top of my head, St George's, Brunel, UEL and Kings with Hertfordshire being just outside. If you go to the CSP site, they have a section about training with a full list.
