Wow, that's going to make for rather a challenge. However, all of us around my age learned to program without the Internet, so it is definitely possible.
I was around 10 years old when I got my "V-tech Pre Computer Power Pad" and was addicted to the BASIC programming program and tutorial.
No internet on there.
But I didn't pursue programming as a career, even though I was very interested in it as a child. Instead, I went the IT route, and have only recently got back into my interest of programming (starting with PHP).
Anyways, I was doing my thing well before high school ended, i knew i wanted to do IT then and didn't use a class to see if I did or not.
I went to a technical school not to figure out if I wanted to do IT or not, but because I thought I needed it to get a job. I was already well into that stuff before starting degree work.
