Duo's also on the app trend of year end reviews and wrap ups, so I thought I'd share mine. I kept up the habit, though I started doing the music lessons too as a break in language lessons all the time.
Also, just wtf is going on in the art department over there? Why is Duo's lil green butt featured so prominently?
Mostly Spanish but I hit my Arabic and Russian alphabet so I can properly anglicize things before trying to translate them but my Latin in college helps with that too.
I feel like I've got good comprehension of reading and to a lesser extent writing but when it comes to conversational Spanish or watching Spanish game shows I'm like a little baby. I dunno if it's all my concussions but differences between dialects and accents just boil my brain.
Speaking to a Spanish counterpart one time, he told me "after a day of speaking English, I'm very tired" and I relate to that.
So, if anything, I think that Duo won't adequately prepare you to have a full conversation but certainly to read or do other activities where people will talk slowly to you.
I haven't tried the math or music lessons yet since they only just added them for non-iOS platforms.
