Hi, if you have done your access course in the past 5 years you should be able to apply straight away.
Would one of your old access course tutors be able to provide your reference? I know ours did for previous students.
I am about to start year 2 of a health professions degree, and I'm in my mid 40s. I did an access course, then applied to local unis, which are still a fair distance for me to travel, so it has been a huge change for me and my family. My course is 50% hospital placement too, and that has been the hardest part for me to adjust to.
However.... I love the academic side, and have done way better than I predicted I would, I kept on top of it all well, but had to be super organised with family, home and uni juggling.
Once over the first few weeks of placement I settled in well and have loved my first year.
What age are your DC? I only have one at home and they are about to start high school, I am a planner, and have had a plan B and C for almost everything to cover unexpected situations. Things have been good, but I have a strong support network, and DC understands why I have to do my uni work, and leave at silly hours when on placement, so that helps.
Good luck, and don't be put off age wise, 30 is young!
