Vocab : I started by katakana word like concert, tshirt etc. You don’t need to memorize the word most of the time as you already know it, but to memorize how it sounds in japanese.
I highly suggest not going blindly into adding a bunch of words, but actually thinking it through and adding them yourself
Then, I added cities (60 words) and “words with no translations” (udon, ramen, futon, tatami, kimono etc)
After that, i added words that were short (one or two kana) and easy (papa, mama, today, this week, this month, this year, etc)
You can already exclude a lot of words from the “unknown” category.
Grammar : As for grammar point, it depends what you’re looking at.
If i take points like “kore”, “sore”, “are”, i grouped them together to study.
Most of the grammar comprehension i have comes from watching videos.
Conjugation : Then, for conjugation bits, people tend to overcomplicate things.
I’ve once seen a book that separated godan into sub groups depending on the conjugation you were studying. Which was useless as godan you simply needed to learn your kana.
Most conjugations can be understood by starting with ichidan which always go : base + inflection (tabe + ru tabe + masu tabe + nai etc)
So you can focus on the inflection part.
Having clear tables help on that side
Like so :
Tabe + inflection
“Positive”
“Present/Future” “Past”
“Polite” “Past polite”
る た
ます ました
“Negative” (same cells but you put everything in negative)
ない なかった
ないです なかったです
(last line can be switched with ません ませんでした, it’s easier to remember just to add です, but keep in mind they’re more casual spoken japanese)
I’m getting carried away, the idea is simply to find a way for you to clearly understand, through videos, books, making your own material etc
Bunpro is a tool to review cards, SRS.
You need to have learned the point to remember it.
Not the opposite.
So if a point is stuck, remove it from your reviews, make a list, go learn about it, then try to review it again later.
