Hello all,
Last December I attempted my N4 but ended up failing only on the grammar section but did very well on the others. I decided that I needed to focus study on not just the grammar but also how the JLPT test questions are structured. To help with this I habe made a site called www.jlptopencatalogue.com.
I know AI makes mistakes but what I have done is gotten it to generate a bunch of test questions by level section and question type, then also built a system to have human verification and review of the questions to make sure they are actually good.
I wanted to share and if anyone finds it useful if you have any feedback it would be wonderful!
Thanks very much!
