I have been using Renshuu for a few weeks and have started "Japanese basics (Grammar)" and "Words for Japanese Basics". According to the schedule I have covered 65 of the 103 words and 4 grammar topics. My question comes from a bit of prior knowledge seeking guidance. I had used Wani Kani up to level 3 and have bought the Genki Books. Does Renshuu mix in Kanji as its own schedule? Is it something I need to manually add myself? I want to eventually use Renshuu in tandem with Genki and supplement with Wani Kani.
