Reset skill tree... bold indeed.
I got the German tree all gold (607 crowns)
I have just re-set it to review it all.
That's cool, but I am afraid you're unlikely to review it all because it seems Duo German is creating a new tree soon. If it took you 18 months to manage the first tree, I wonder how long it will take for you to redo it before Duo team deletes it and updates to a CERF course. All your current progress will be lost :(. (But good news -- that would also imply you can redo your German with new words and added skills once it's updated! I think it won't take them too long to do that).
Also, just curious -- why not the reverse tree?
I am not really bothered about visible progress being lost.
I am not sentimental like that.
I am more interested in my own progress, so i am happy to lose progress as shown on the site.....
I am doing the reverse tree too.
i will probably re-set it again when i get the new tree..
