Go for it. Another thought is that often you can just attend the lectures without paying. That may be all you need.
If you download bittorrent (www.bittorrent.com), you can download a lot of textbooks for free. If you'd rather have a teacher, that's different but you can also just download the texts and use your laptop for class to save money. I know other students who do the same thing :)
Why shouldn't you? Go for it. The toughest part will be walking into class for the first time. But I know from experience that your lecturers and tutors usually enjoy having a mature person to teach for a change.
IfII am still compos mentis when I retire, my ambition is to do a history degree. Don't have the chance right now as I am working full-time.<br />
Go for it, if you can! (turning green..)
Why not?<br />
When I was in college there were some excellent history professors who gave great lectures. I didn't sign up for the course, I just went to lectures and enjoyed them.
Just go do it!
Why on earth would you NOT?
Yes, it would be fun!
