Additionally, this project, much like its predecessor, is open source, so you can view the code on GitHub as well as contribute improvements, fixes, etc. It can also be downloaded and used offline for when you may not have access to the internet.

Though I'd recommend getting a textbook like Genki and just working through the exercises in there. That way you'll learn gramar and put it into use right away, so you wont forget it. Plus the exercises are fun! There's audiofiles and everything. You can also do the exercises here https://sethclydesdale.github.io/genki-study-resources/lessons-3rd/

There's also an online web where you can practice Here

Genki still remains one of the best ways to cram Japanese into your brain effectively. Someone even digitized the genki workbook so you can do it online

And for reviews/quizzes, and other practices: Genki Study resources Genki 3rd

I found Seth Clydesdale’s genki quiz website more beneficial.

You should buy the answer keys and workbook. However, there is a great online resource here https://sethclydesdale.github.io/genki-study-resources/lessons-3rd/ which has most of the exercises available and checks the answers automatically for you. So you may be able to save money and skip the workbook and answer key if you want.
