this was so valuable thank you for the response !!
what kind of words/sentence structures are the most challenging for continuers in your opinion? just so i can gauge the overall difficulty of the course lol
		
		
	 
honestly, i'd say the difficulty of learning the rules of each sentence is not necessarily more or less for any individual sentence, but the difficulty comes form memorising all the many, distinct rules.
for each new sentence you learn there will usually be a separate rule for nouns, adjectives, verbs.
japanese comes with an endless amount of ways to manipulate/change the tense, modality, formality etc and you'll have to combine all these different things
with vocabulary, (if you're using the wakatta textbook) id just say every time you get to a new unit skim through the quizlet of the previous unit because they're all available online. any word thats completely unfamiliar, keep track of it and save it to some separate flashcard set (like anki/physical ones)
some vocabulary may seem really really useless (and those tend to be the 'difficult' ones) but examiners LOVE throwing those in assessments
like, i remember coming across 'municipal office' and shrugging it off at first but being so incredibly confused when it came up in an assessment, lol
sure, you have your dictionary available during assessments but its time consuming and isn't guaranteed to help, its more of a last resort.
id say, even if you're naturally talented at japanese, doing minimal work will keep you stuck in the 80s, which isn't bad, but putting in a bit of extra effort to fine tune any small errors is what will push you into the high 90s range.
if you're doing extension though, these habits are going to be a huge help implementing early on
what makes japanese hard is the amount of content that there is to cover, not necessarily the difficulty of the content itself. it can just be a lot.
but it doesn't have to be overwhelming, as long as you're practicing often.
if you ever want to hear more specific details about any part of the continuers course, like how to practice or prepare for a specific kind of task (listening, speaking, writing, reading) feel free to ask !!
