I've been studying with subs2srs cards for a while, but I'm not exactly sure how I'm supposed to. Do i just pass the card if I know what they're saying, or do i repeat what I'm hearing, or what?

Thanks for any help.

My take on using subs2srs:

* For new cards: If I know a card really well, and have no trouble understanding it the first time through, I delete it. There's no point in studying such cards, so I remove them from the deck. If there's a new word in it, or it sounds　like a jumble of sounds that ends in ですよ, I listen to the clip several times, then I fail the card. I put notes in the card as to vocab or grammar I didn't recognize.

* For repeat cards: I make sure I can get what they're saying just based on the audio alone. This may take a couple of listens on harder cards. If I still don't get it after a few lessons, I listen to it another time or two with the subtitles showing, and then I fail it. If I repeatedly don't understand it (e.g., it's full of colloquial contractions, it's a dialect like 関西弁 or 東北弁, etc.), I will Mark and Bury it.

* Once a week, I review my Marked cards with a teacher on iTalki who can help explain some of the contractions and dialectical snafus that I didn't get the first time through. I add my teacher's notes directly to the relevant card for later review.

Make sure your cards contain enough context for you to be able to follow what's happening. I include previous and subsequent lines on my cards, and add two seconds of audio padding before and after.

But do whatever you want - there's no one proper way to do things. If it's easy and you're retaining things then it's good.
