Started back to school myself at earlier this year at 51. Had to retire from the fire service after 25+ years due to back issues and nursing has enough diverse fields that I'm sure I can find a job that would be a good fit for me. Starting back after not having taken a college level course for over 20 years was a bit of a shock. Hell, the last time I took college classes, there wasn't even computer registration. I had to stand in long lines and turn in papers hoping the class wasn't full yet.
The hardest part for me was trying to recall concepts I hadn't even thought about in such a long time. Luckily, most of the pre reqs I had taken years ago were still accepted. I only had to retake A&P II and psych 101 and will apply for admission to the nursing program in December. I don't know how I'd have handled taking beginning English or math again.
I haven't found anything more difficult then I expected. And with COVID, I have taken all my classes online so I haven't had to deal with all the students calling me "Gramps" yet. I do the majority of my classwork while I work nights at a VERY slow police department as a dispatcher, so time management isn't an issue. Though I'm sure that will change when I get in to the actual nursing program.
Any questions, feel free to hit me up.
