How much time does it take a Portuguese course - an answer
I just finished a Portuguese course. It took two months of learning everyday for almost exactly two months. I was learning for approximately one hour a day. Towards the and of the course you get more motivation so I spent probably more time on learning in last two weeks.
At the end of the Portuguese course I have: 9983 XP, 63% of Portuguese Fluency and 272 lingots.
I'm so happy today!
Congrats to all those people who finished more than one language course on Duolingo!
What happens after you complete the whole language class: you keep forgetting words. :) So each day about 5-8 lessons get their colours back (instead of remaining orange) and you have to strengthen these skills. It takes about 20 minutes a day to keep all lessons orange. Of course, you still earn XPs, day streaks, levels and lingots for practising.
