My experience doesn't really match what you are asking, but I wanted to add that hopefully your education never stops. I consider myself under-educated in a formal sense (BS in Physics about 50 years ago) so I have always invested heavily in books and the time for self study. In the last 12 years, I have taken a large number of online classes.
Obvious advice from me: if you can afford it and want to go back to school, go for it! I would take some care in choosing a field with good future employment prospects. Good luck.
