I've tried other courses, learning some German but always struggled. This course has staying in my memory from the very first lesson and I'm very pleasantly surprised. It can be a little intense covering a lesson in full - I have chronic fatigue - but it's worth the hard work. Even with my problems, I'm learning solidly. The case system always broke me because it's taught too rigidly. I'm already using prepositions correctly when talking to myself around the home because Rocket appears to be teaching me to hear what's right or not. Glad I didn't quit and signed up to Rocket instead.
