I like to keep up with my classic review as much a possible. I usually make sure I’m at a reasonable level with all levels before I move on to the next one.
However, it is very tiresome to have to move back and forth between each one everytime. Especially since i rarely have more that 5 on the earlier levels of my Japanese course.
I therefore suggest to the devs that they make a ‘shuffle classic review’ which spans all of the levels of the given course. This would probably make most sense for Official Memrise courses only.
Alternatively, you could make it possible to ‘start a shuffle classic review session’ and then you could manually add the desired courses to the session. That session might then be saved for when you come back.
If you support this idea, please make it known in the comments.
