Your study and how you divide it changes depending on the language in question, where you are up to, etc. Iād say, generally to focus on your weaknesses.
If your goal is to be able to understand and speak to native Italian speakers, you should primarily focus on vocabulary used in spoken language and listening comprehension (mainly pronunciation/accent and speed). At least, I found those to be the main issues I had when I was aiming for such a goal in Italian.
If your goal is conversing with and listening to native speakers, you have to make sure you are studying the right material. You should be focusing on YouTube, podcasts, and/or Netflix. This canāt be stressed enough. If you are reading Harry Potter and listening to audiobooks, it will only take you so far.
The question you may have wanted to ask was How would I split my active study time to achieve this goal? My passive study is pretty much set in stone, as I want to listen as much as possible, but the exact amount is usually determined by my lifestyle on that exact day. With regard to my active study, Iād say 90% of it was reading while listening (or pre-reading to do it). After Iād pre-read once (only necessarily when there are lots of words you donāt know), then 2x re-read while listening, I added the audio to my playlist, where I would passively listen to it when on walks, commuting, cleaning the house, etc. I expose myself to new vocabulary in active study, then drill the word into my memory with passive listening while practising my listening comprehension (as I remember the content of the audio from studying it already 3x in active study).
In my active study, I did very little grammar study for Italian. Only a little here and there to mix it up or when curious. I just found that Italian grammar wasnāt much of an obstacle to understanding for me at the beginner to lower intermediate stages. As for speaking, you can do as much as you want, but I think itās better to hold it off, if you arenāt in a rush. You just get more bang for your buck from the above-mentioned routine, because you canāt say anything, if you have a low vocabulary.
I notice your stats: 1.09M words read (known words 2,184; lingQs 21,680; lingQs learnt 1,004; hours listened 275)
Compare these to my Italian stats at the time: 1.1M words read (known words 10,332; lingQs 28,433; lingQs learnt 6,489; hours listened 302; hours of speaking 13)
How are you studying and what material are you studying? Are you hyper conversative in marking a word as Known? I consider myself to be reasonably conservative in marking a word as Known.
