at this stage, really do anything that makes it easier for you. turn on that furigana, take all the hints. consider switching to a mode, that feels the easiest for you. you can alway reset n5 later and redo it in a harder mode.
when i started bunpro, i didn’t have much grammar, but already had most of n5 vocab, and reading those sentences was still hard. i recommend getting a few more vocab in, by any means that you enjoy. maybe just flashcard style, even. (again, you can reset later for full sentences).
another thing to work on, that i highly recommend is, learning to deal with ambiguity, just not knowing things yet and making lots of mistakes. sentences full of words you dont know? not a problem, you aren’t supposed to know these yet. just look at the translation in the end, and see of you can match some words. it’s good practice even if you’re wrong, even if you don’t realize you’re wrong. just by training you to think and notice patterns, you’ll progress.
don’t worry too much. yeah, it’s hard. yeah, you make a lot of mistakes and don’t even know what’s correct. but that’s just part of the progress. it might feel like you’re too early, it might feel like you’re not cut out for this, but that’s basically what everybody goes through. you can safely ignore those doubts and reframe them as “the rookie part” of learning a language.
