Revisit old lessons until finish with full hearts OR just plow on?
I was just wondering what you recommend as the best approach to learning with your lessons. Should I keep revisiting lessons until I finish them with full hearts, having made no mistakes? Or should I move on when I finish a lesson and just forget about the fact that I barely squeaked by on that last German lesson?
There was a large discussion on that: http://duolingo.com/#/comment/223366
It inspired me to go back and get my full hearts for every lesson. I found that I don't remember a lot of words because I always moved on after barely passing the lessons. I'm almost finished with the previous lessons and from then on, I'll be getting full hearts for every lesson before I continue.
However, as far as I understand, the new system which is coming soon has no hearts but only strength indicators.
