How to stream through the learning tree?
I notice some people will master each component of the stream and get gold while others will just learn enough to open the next learning section. Some have lots of gold boxes in their stream for one language and another language will be green and blue boxes.
I wonder If I'll learn faster just to learn enough to level up and worry about mastering each section?
That is probably personal preference. I like to master each skill before I move to the next one; and every so often, I do timed practice to repeat the new vocabulary.
That's up to you, ill recommend to do a lot of practice rounds before advancing to new levels since you may be not learning all the words and structures if you go to fast, but again is up to you. Good luck!
