No way will Duo Lingo get you anywhere close to A2 for writing or speaking. MAYBE A1 if you try hard at it for a long long time in a language it well supports.
To get to A2 you need a real tutor and real communication experience. I used Verbling to find a tutor and I traveled to Eastern Europe over the summer to practice and only after hundreds of hours of practice was I able to communicate in Russian to any degree even approaching A1.
