obe_TIL scheme is a common-ish intro level language. I thought my uni was just dumb.
The uni I went in, which is/was the best engineering uni of Portugal was the only one in the country that teached scheme and that used it as an intro level language I never saw it used anywhere else either, all other engineering colleges in Portugal use Java or C for most of them as an introductory language...
It's a pretty useless language imo and very frustrating to learn which is why I think most people fresh in college have huge issues with it. I just wish I could have started with Java or C like all the other :(
