Welcome to WaniKani! I’ve been studying Japanese for years, and this is the only Kanji learning method I’ve consistently stuck to and seen results from, I hope it’s a good fit for you too
It all depends on your learning style, but four things I’ve found helpful:
*Say everything out loud when learning (and when reviewing if you’d like), including the example sentences. They can be a bit weird, as they’re often missing the kanji you haven’t reached yet, but it’s still good practice and easy to add.
*Ignore the speed runners! Especially as you’re studying Japanese outside of WaniKani, slow and steady is likely to be more sustainable and help you remember things better.
*Similarly, keep an eye on the number of apprentice items you have on the go. Those are the ones you’ll see most frequently coming up in reviews. For me, I like to keep that number somewhere around 50. If it tips over 100, if I just feel a bit overwhelmed with the number of reviews coming up, or if I keep making mistakes, I just stop doing new lessons for a few days and focus only on reviews.
*Lastly, WaniKani is great for recognition, but not recall. So it helps you read Kanji, but not necessarily write them! I’m sure you’re getting outside practice with this, but if you want to supplement it, try KaniWani, KaniSame or Kanji.sh. There’s plenty of info on them in the community.
Good luck, and most importantly, have fun!
