@Aramaruma, I was in the same spot as you at level 6!! I had only glossed over any “how to” and had not really participated in the community - I just jumped in and cleared my lessons every day. If you are interested in how that went for me, you can read this thread about my experience as a cautionary tale :laugh:
Pace your lessons, try to hit your 4-hour reviews more or less on time, don’t let reviews pile up. If you feel like you aren’t getting enough learning out of that, try spending more time on grammar, reading, and listening skills, maybe sign up for a conversation exchange like Tandem. That will help you more in the long run than racing through the kanji. Knowing more kanji is not helpful if you can’t actually understand the language.
