I’ve been using Anki for about two months to study Mandarin. My apologies if this is the incorrect forum for this question. I have cards with review dates far in the future, however I’ve forgotten the cards. My guess is I did well learning & reviewing a few weeks ago, so the review date got pushed far into the future. However, now I’ve forgotten the stuff. I use FSRS. It’s possible I’m forgetting cards I reviewed when using SM2, before I switched to FSRS. Should I reset these cards? ---

If your collection is not too big, I might consider using the reschedule all cards option in the fsrs helper addon menu. There might be a better option, though, and I’m not sure what the best course of action is if you have a lot of cards. ---

Have you re-optimized your FSRS parameters recently? That might help fit the scheduling better to your memory curve. You can re-optimize monthly. > [@mandarin7345](#): > > I have cards with review dates far in the future, however I’ve forgotten the cards. If there are cards _you know_ you’ve forgotten already, you can find them in the Browse window and use “Grade Now” to grade them Again. They’ll lapse into Relearn so you can study them today. > [@mandarin7345](#): > > It’s possible I’m forgetting cards I reviewed when using SM2, before I switched to FSRS. A couple options there – - Install the [FSRS Helper](https://ankiweb.net/shared/info/759844606) add-on, and run “Reschedule” on all your cards, or any specific group of cards. That can cause cards to be rescheduled into the past, and become overdue, so that might give you an instant backlog. If you don’t like what you see, you can `Edit > Undo` to put them back. - Go fetch a small batch of those cards so you can do a study session with them now. You can make a [Filtered deck](https://docs.ankiweb.net/filtered-decks.html) of cards that have long-ish intervals that aren’t due for a while – with a [search filter](https://docs.ankiweb.net/searching.html#card-properties) like `prop:ivl>=90 -rated:X prop:due>=30` [cards with a 90d+ interval, that you haven’t studied in the past X days (how long ago did you enable FSRS?) and aren’t due for the next 30d] – or whatever numbers make sense in your collection. FSRS learns from you studying cards, so if cards it has scheduled far in the future are already forgotten, that will be good information for it to have. It’s probably also worth taking a look at your grading habits, your parameters, your Desired Retention [DR], and your retention results – to see if there’s a problem. - Are you using the [grading buttons correctly](https://docs.ankiweb.net/studying.html#answer-buttons)? - Are your retention results [Stats \> Retention] staying close to your DR goals? ---
