Hiya,
I carried out an Access Course with the Distance Learning Centre, while it wasn't for Nursing it was in another healthcare field. If you are looking for an online college to just get it done, that will be more than sufficient. There is very little engagement with other students (if any) and little contact with your Tutor unless you schedule tutorial calls or ask for help with specific tasks. Ultimately you are teaching yourself the subject with about a Unit a week or two for larger credit units. This worked perfectly for me as a mature student with a life beyond education and working full time for the NHS.
I certainly struggled at times, but it made me a much stronger learner as everything I learned was on my own. It's not for everyone, but I certainly didn't want to attend a local college several times a week so this did the job I needed it to. Now I'm am off to St George's in September to study the degree I wanted, something I wasn't even sure I would be able to achieve if you had asked me 8 months ago.
Give us a shout if you need any more info/help.
