Usually, the multiple difference corrections on my entries confuse me. I have no Idea what is the best correction, but at least some people put more effort into making it readable and comprehensible by showing the changes and ears in a clear way. Those are the ones I tend to mark as best.
What I don't know how to do, is remember how to actually use those corrections to learn. Flash cards are not bad for vocabulary but I have such a backlog of words because I can't remember them. Hmm, maybe I could clear out the backlog of ones I can't recall, and just work with these ones because at least I have context for them.
Perhaps same with grammar points.
