No, Memrise does not handle “overdueness”.
If you have paused for months, the best probably would be to transfer all courses over to Anki with the Memrise2Anki exporter.
AnkiSRS is more powerful, supports overdueness out of the box and you can use the Anki application browser and ordering for different stuff.
For example you can create special filtered decks, where one supports the overdueness filter, which shows you the words which are more important (shorter in SR interval) sooner than those which have a longer SR interval.
Cooljingle’s Memrise user script “Catch Up Review” is disabled and does not work anymore because of a Memrise code update several months ago.
This would have been your best option, to kick those intervals further back out from the “standard Memrise SR intervals”, if you still know some words.
I would NOT reset the course and start from scratch, as you may still know some words with higher SR intervals (e.g 90 or 180 days).
On the web portal you can set the review word count to 100.
With the “Infinitive learning” user script from Cooljingle you can catch up pretty easily (polls the next batch of 100), or stop reviewing before you hit the 100 words count…
To get the review backlog queue down to zero in the most easy way is to use:
- multiple choice questions
- speed review
I am not really a fan both of those, since I was using Cooljingle’s user script “all typing” for reviews on the web portal for avoiding false positives (marking words to know and push back the SR interval, but actually NOT knowing the word 100%).
If you do not want to switch to AnkiSRS and prioritize reviewing words by filters or ordering, personally I would just try to run 3-4 100 word sessions with “all typing” (=RECALLING) per day and see how fast you can get the huge backlog down.
If it takes more than a few days / weeks…who cares…
The missing of all/some “useful features” can not make Memrise to one’s favourite platform.
Basically you can only use Memrise web portal, if you do daily or weekly reviews…
