I have a big exam in 69 days, but I don’t know what number to put in the desired hold that would be appropriate for that period of time . When I put that period in “Compute minimum recommended retention” it gives me 0.75
Should I put the “Compute minimum recommended retention” number instead of desired retention?
Do I have to change the desired retention number every day according to the Compute minimum recommended retention?
Or if I don’t change it every day, how many day times should I change it?
Should I reschedule all cards all the time when changing desired retention ?
Do I need a filtered Deck or custom study (to review all cards) 2-3 days before exam time if I use FSRS ?
Choose a high-but-not-crazy-high value of desired retention
Set max. interval in a way that ensures that you will see each card at least once before the exam. For example, if exam is in 90 days, set max. interval to 45 days.
(optional) use the Advance feature of the Helper add-on to study cards ahead of time. It’s basically the opposite of postponing
That has happened to me (for a deck I am studying since 2023)
By the way, any specific reason you put the same number as 270 in there? I think you may have misunderstood how this works. You can put a higher number and you’ll basically get a similar figure (± a few percentages).
Assuming that the algorithm works accurately for you and you rate the cards correctly, you don’t need to use filtered decks before the exam. However, if you don’t want to take any risk, you may want to use filtered decks before the exam.
No problem. It just means that the algorithm has determined that 0.75 is the retention at which you acquire the most knowledge per hour spent reviewing.
However, for exams, you likely want a higher retention. Say, 0.90
You should optimize the parameters at least once. However, they don’t depend on the desired retention. So, you don’t need to re-optimize them after changing the desired retention.
Usually, I don’t recommend rescheduling all cards because it can cause a backlog. However, because you have an exam soon, it would be best to reschedule all cards so that you can reap the benefits of FSRS as quickly as possible.
I have never tried reschedule though I would like too (for my super old cards). I just don’t know whether it shows us “how much backlog” will we create. Do you know whether something like that is shown (maybe with a popup)? If not I think it would be a good feature to add.
You can reschedule all cards using the FSRS Helper add-on. It has an advantage that you don’t need to change the parameters or desired retention to reschedule. If the backlog is too high, you can simply press Ctrl + Z.
I changed the desired retention to 0.90 and I optimized parameters because i wasn’t optimized parameters for 25 days and i Rescheduled all cards . now I have 112 cards for Review(duo) but it’s good some card interval is after exam ?
Well, in spaced repetition, intervals grow continuously (unless you fail the card). So, it should not be a surprise that some cards would be due after the exam.
If you have rated the cards correctly in the past and you trust the algorithm, then don’t worry. If you have any doubt, you can do custom study close to the exam.
