Hi - congratulations on being accept for pre-reg nursing, that is a great achievement! Have a look in your local paper for jobs in care homes as care assistants, but also look at the national NHS jobs website www.jobs.nhs.uk
where all the vacancies - at all levels - in the NHS are advertised. You may be lucky and find some short-term agency work by registering with your local NHS bank. Don't worry about not having the NVQ as yet, that is a requirement for some NHS HCAs, you would have to work towards that if you were on a permanent post but you are going on to better things starting in January! There are a couple of jobs at the moment (it depends where you live) if you put "Health Care Assistant" in the Search box on the NHSjobs page, quite a few come up, and there is at least one for a Bank job. You have to register and apply on-line these days for all NHS jobs - goodluck!
