A friend of mine embarked on the course 3-4 years ago. She was mid 50's then.
She got on well with the medical side of things. The driving side was ok for her and the university stuff was manageable. Put the 3 parts together and she found it stretching, as there is hoop after hoop to jump through.
Once out in the road as the number 2 of a pair she really enjoyed it, though the shifts meant we rarely saw her. When we did she was knackered!
She was at stage 2 of 3 parts to become a full paramedic (at this point she was an ambulance technician or something, I can't remember the term)
She had to do Certain amounts of training on certain things, with qualified people, but wasn't being allocated the time, yet she was actually asked to be the number 1 in a crew and have a raw recruit as her number 2. It was this kind of organisation cock up and bad practice that made her pack it in. She felt that it was all a bit 'skating on thin ice'
She now works in patient transport.
