I'm also learning Japanese using the Genki books (it's only elementary Japanese, but better than nothing). I already know Hiragana and Katakana (which went quite easily) but the vocabulary is kind a harder on me since languages are not my best subject. But luckily I'm doing because I want to and not because I have to so there's still hope

The Genki books are in total 23 or 24 chapters. I'm hoping to have the first volume (12 chapters) finished by the end of this year and the second volume by July next year. Would be nice if I actually make it
