You can filter tag by WK level. They have tracked studied ‘known’ words system as well ll. The WK API is coming soon but it’s not necessary if you want to filter what you already studied. It’s not just a vocab deck, it teaches reading & listen comprehension with sentences plus in all in one system for Eng → JP which has always bothered me with WK. And the content is pretty polished given the community feedback loop.
Everyone is different and I’m still a student of the language. If you have awesome retention to pick up vocab or have a passion for reading and willing to do ALOT of dictionary look ups, go for it. Others will feel a mountain of unknown vocab that is scrambled to retain both reading and listening comprehension so SRS helps a lot and there are creative ways to utilize it other than just vocab…then you can close the gap a bit better for on native material.
I think everyone navigates the intermediate plateau differently with personal goals in mind. For listening to shows/YT/drama/anime, you need reasonable reading skills to read the JP subtitles quick enough (and accurately) for adult content…I find this helps to know what you are missing by ear to help close the gap. I’ve done alot of passive listening through the years beyond my level and it can largely be a waste without an active study component. Full time immersion is great if you have no other responsibilities and can do 8+ hours a day of media. But I need time effectiveness and SRS helps along with a fixed schedule…but it gets boring too so I mix media and conversation as such towards my own language goals.
