Hello! I've recently picked up learning Spanish because I work with a ton of dudes from Mexico. How much can I reasonably expect to learn from this app? I looked at their "curriculum" and it seems pretty short compared to what I think I'll need. What are some resources beyond "talk to your coworkers", that will put me on the right track?
What kinds of concepts were you forced to relearn?
I'm afraid I can't remember any examples as I haven't used duo for well over a year now and have moved on with my learning with the 2 things I listed. On a few occasions though when I thought that I had learnt something new that I could use I would try and use it and my Spanish gf would flat out say what I had been taught was straight in correct.
Less relevant to you is that it teaches south american Spanish which to me is a bit disingenuous as the "course" is called Spanish and has the Spanish flag I expect to be taught Spanish spanish but instead they teach words like computadora that just would not be used un spain. Conversely busuu will teach you words from all different places but also tell you which are which rather than no explanation what so ever. This was more an annoyance to me in addition to other glaring issues that I can't fully hold against it but will due to spite in terms of my wasted time.
