Points for practicing old lessons
It would be nice if you could get a nominal amount of skill points for practicing old lessons, even ones you finished with three hearts. I've been going back this week to review lessons I wasn't as confident with and it's been helping a lot, but by points it looks as though I haven't been doing anything. Not a big deal, but would be a nice touch.
You can get more points if you want. If you want to practice old lessons don't push in the lesson or in the exercises. Push just below of them, in "practice" button, you will get the same exercises and you will get the same point than in regular lessons or even more points if you make the timed practice.
There are two main reasons why a user might prefer to redo a lesson than practice.
First, skill practices don't affect the heart progress for each lesson. As the course becomes more difficult, more time and effort is needed to achieve the 3 hearts.
Second, redoing lessons is the only way to practice with fewer and more focused vocabulary. Some skills have over 70 words, which can be overwhelming.
With both, the reward and progress is very small and disproportional. This is what Kaylastack and the others are trying to pointing out.
Actually, I agree with eunoia on this one.
I find the Practice Session, especially Timed Practice to be a bit overwhelming and prefer to work on each unit by itself (and add hearts to my heart collection.)
My learning style is memorize first, learn grammar rules second. So far, this learning style has worked for me and with practicing a unit multiple times I can work on memorizing the sentences.
