Did a master's in maths with the internet in front of me the whole time. Learned almost entirely from textbooks on my desk. The internet was useful for discussing problems and ordering books from the local library.

The secret to my success was reading the textbooks and working through them. Had perhaps twenty days of formal instruction throughout, but when I added up the hours spent it was effectively me and the books for a time equal to eight months' full-time. Couldn't have done it without simply hitting the books. Can't speak for your chums. Maybe they learned in classes or lectures or practical sessions or some such. For me, it was hitting the books.
