Yes, don’t give up . As someone who finished Genki 1 & 2 very recently, I don’t think there is any special trick to it. Just some minor considerations:
- writing things on paper, especially kanji may help you remembering kana and kanji better
- “production” exercises (answering questions, writing short paragraphs, etc.) are definitely worth going through properly
- double-check vocab with a dictionary; some translations are not entirely correct
- don’t shy away from using kanji outside of the recommended set, even if Genki doesn’t do it ; however, check with a dictionary which words are “kana-only” to avoid using too much kanji
Other than the usual topics, https://community.wanikani.com/t/japanese-sentence-a-day-challenge is a great place to flex your budding grammar skills. You’ll definitely get feedback and maybe strike some related grammar/vocab discussions with the usual lurkers .
