I want to find a good German course. I know there's Duolingo, Babbel, Rosetta Stone, etc., but I find they don't work for me.
I want a course like the ones from 15-20 years ago that would give you some text books and some CDs for listening exercises.
I started learning German with one of those that my dad had, but unfortunately the audio lessons are incomplete.
I'd like to know where I can download/purchase a course in that format. I also prefer that format because my internet access is intermittent so I want to be able to study offline.
Ah, it sounds to me like you're wanting something kind of like the old Pimsleur German CDs. Looks like the current iteration is a subscription model with option to buy. I only remember the mp3s I downloaded years ago.
This is coming rather late, but I would definitely recommend Language Transfer. It's a series of MP3s, that you can listen to on their own, or use their convenient app. The whole thing is free, although they are happy to accept donations.
