Hi Fluffpaw how's it going? Before I start I'm working in London so things obviously aren't the same, but I think I have some empathy.
I finished school at 18, and went on to apply to Uni to do a Paramedic science degree. I got straight rejections from several Unis (almost certainly due to my age/lack of experience) until one decided to take me on (idiots :roll: ). The selection process involved interviews by both the sponsoring service & academic institution.
I'm now in year 2 of a 3 year course, currently working 2 weeks on & 2 weeks studying. Thinking back now I probably should have waited and not let the enthusiasm get to me, you never seem to realise how crucial the "life experience" thing is until you do the job for real. However on the other hand, I can't think of a better way to get life experience than doing this job, so its a bit of a catch 22 situation. When I do work people are shocked when I tell them I'm only 20, and to be honest it scares me to think I'll be a Paramedic at 21.
emt019's post is excellent advice mate, so I'll chip in too with advice along a similar vein (having been in the same situation): Don't be afraid to wait a bit before going head long into the mad house known as pre-hospital care..
Sorry if any of this seems patronising, good luck with whatever you decide to do 8)
