I stated with Duolingo. I frequently needed to consult “Professor Google” to understand “why this word order” “why leben and not wohnen” …and countless other issues. I was spending more time on Google and less in Duolingo. Now I’ve found German Stories and have started the free trial period. WOW! What a relief to find such a well thought out and intelligent approach. No more need for “Professor Google”. I thank Christian and the entire team.
