So most importantly if you have a child who doesn't want to study or has disabilities, obviously it's not guaranteed to work but my kid does it and i haven't had to ask a single time, she does it probably at least and hour a day, playing chess, learning Spanish and math, all things i thought were fantasy, anyways you get the point. As for me, that's why the title is because I am wondering how far it can get you off pure studying nonstop, eventually it's better to have someone fluent to speak to in order to improve but learning words, sentences and writing, yes, keep in mind i'm putting in hours of work, but Russian I needed to improve, that's going very well. I also wanted to see how it would do with languages I had little to no experience in. So rather than explain tiny details, I think the fact that I can read and write some Japanese and haven't even gotten far but I mean, Japanese is completely different when it comes to writing, and I had no experience, but I wanted to see if I could read It if I wrote some stuff down can I read it in a while. It didn't look like nonsense to me, I could read and understand some of it. I recommend doing lessons longer getting a pen and paper and write down every single sentence to practice writing and grammar. Again, no clue if this'll be for everyone and you have to put in the work, don't expect improvement not taking it seriously. Anyways, i'm gonna wrap this up, I hope this helps if you're on the fence on the plan. Chao
