Becoming a paramedic isn't particularly insurmountable: it's mainly about qualifications though. Most places will ask for 250-280 UCAS points, and you'll need to get some experience in a care environment. Auxiliary nursing is a good one, and getting involved with the Community Responder scheme is another. Fees are of course now £9,000 a year thanks to the ***** in power. This can be borrowed and the usual system of grants etc is available.
