Hi there !
I’m using Memrise since months and i’m at the 6th of the 7 levels. My feature request is about all the things learned since the beginning. Because time after time the first lessons are way too far and it could be good to remind them up from my mind. When i finish my daily memrise time, I always think to myself, it would be great if I could use a button to have a mega random reminder from all the lessons i’ve been through. The idea should be selecting on a list to revisit all what we learned in a way we want : pronouncing or earing or typing, etc.
Thank you 
Florian
I don’t know whether this is exactly what you’re looking for, but - on the web - you can select a single language from the filter drop-down. Assuming that you’re only learning a single Memrise course, this would give you the 6 courses that you have been working on. Once selected, you can click the blue Review-button to its left to review the words that are up for review across all courses of the selected language:

This is, however, limited to the web and to the words up for review. These may or may not include locals-videos and audio tests, etc…
Another “hidden feature” is the difficult-word (DW) review across all courses. You can find these here:
https://www.memrise.com/home/difficult-words/
To locate them from the dashboard, click the More link in the statistics section on the left, then click the Difficult Words link near the top right.
If you then open/expand a course, you’ll see all DW of the selected course which can then be reviewed from there.
Again, this is also limited to the web, i. e. you won’t find this in the apps.
