after completing tree
after I complete my tree how well will i be at speaking spanish?
It depends of you, if you practice every day you will speak spanish better than if you practice once a week. I am spanish, and i completed my tree. I don't speak english perfectly, of course, but i can communicate with other people that speak english. All learn at different rates.
If you practice i assure you that you will can speak spanish pretty well. Merry Christmas!!
The answer depends on what you do in addition to Duolingo. If you only use Duolingo, you'll barely be able to speak at all. If you practice speaking with a Spanish-speaking friend, you'll learn to speak reasonably well. The emphasis in Duolingo is more on reading, understanding spoken Spanish, understanding how Spanish "works." Speaking is a separate skill.
It depends. An analogy would be completing a year of Spanish at a university. Some folks study hard, get good grades, and speak reasonably well, Some folks just get by and can't order a taco at a Mexican restaurant. ;)
