Harvard Extension is a bargain compared to most colleges. $1500-$2500 for most 4 credit classes. Don't tell those smart college students that you are getting the same class for less than half the price. I tried the online thing (Coursera, edX, Udemy, etc.) but was never as motivated as competing against real students in a real class with deadlines that have consequences. Fear of failure is a great motivator :)

> Did you do all classes online or did you go in person for some / all?

It was a mix. The online classes were more time efficient. The person classes built rewarding personal relationships with faculty and older students.

> Did you work in technology previously?

Yes, was primarily self taught. Only had access to a lousy community college in my teens. Turned me off school then.
