Bunching weak topics...
There are a couple of things that I struggle on in German. For instance, defining which is which when it comes to dative, nominative, and accusative; But I have to go through each individual topic and can only practise one at a time. So then I know what I'm going to find in the work. It's not providing as much of a challenge as I'm looking for in strengthening my skills in cases.
I think it would be a good addition to be able to parctice multiple topics at once. Bunch them together and make a longer lesson, so you can get decent practice on each topic that you chose.
It would be nice for something like this to be implemented, I think at least. Let me know what you guys think. :)
