My sister has just completed the two year course at Oxford Brookes. She actually got in on the back of having done a sports and exercise college course (instead of A Levels) and having trained and worked as a life guard. She was pretty much the youngest person on the course - just turned 21. Most of the other students were older and had done other jobs, many in the sports or healthcare sector. She applied to a few places but this is the only one she got into.
She's found the course pretty tough, especially with all the night shifts - three in a row sometimes. Also, she had to get into debt to do it but I believe that's changed now.
She loves it, but I personally can't think of anything worse! It seems to swing between the routine (picking up elderly people who've fallen over) to the horrific (witnessing people die in car accidents), and can be emotionally taxing - she says that the only people who really understand what she's going through are other paramedics. You also need to be physically strong as there's lots of lifting involved.
On the other hand, she finds the work stimulating and always has plenty of stories to tell. She loves driving the ambulance and meeting all the people she treats.
You need to think about the other end though. I gather that where you are able to get a job will depend largely on where you did your course. So because my sister did her course in Oxford, she was able to get a job at an ambulance trust in Oxford or the surrounding area. Are you able to attend a course close to where you already live? Otherwise it could mean uprooting the family.
The other thing, of course, is that the pay is outrageously low IMO.
Good luck to you, whatever you decide to do.
