I had a classmate who started at 63, and graduated on time! She had some experience earlier in life as a Rad Tech, so she knew what she was getting into. After graduating, she had a tough time finding a job, eventually settling for something not too strenuous, working for about a year or a little more, then retiring. Overall, probably not a great financial investment, but it was an itch she needed to scratch. There's a lot of good advice already given, so I won't repeat it. Best of luck, and if it's your dream, go for it!
