What do you guys mean when you say you have done a reverse tree? Do you go backwards?
When would I probably be able to start to do a reverse tree from Ger>Eng (I am not native German speaker of course)? Would I even be able when I get to level 25 in German? Would it help my German to do a reverse Ger>Eng tree? My English is excellent. Thanks in advance. BTW, I see that you're into astronomy and physics, so am I.
