Terminé el árbol español!
...and today made the tree fully golden! It took just over 3 weeks.
Now what? I am thinking I try to keep the tree golden (at least weekly if not daily), start on the reverse tree, study grammar rules (spanishdict seems to be good), and listen to some podcasts.
I wish there were more rules/tips on duolingo, especially in the verb skills. Only the early skills had tips.
Thanks! I have also just finished Spanish too. I plan to hang on duolingo just to master everything and keep my streak. But it is so helpful that you recommended another website!
Congratulations! The Spanish dude YouTube channel has some good tips on learning verbs.
