Hello, I think I finished all the activities in the Spanish section, but I continue to get reminders. There are two bonus sections that I haven't unlocked because I don't have enough lingots. What's next? How do I make further progress and continue to earn lingots? Thank you.
I suggest that you repeat the lessons you have already finished or do the inverse tree. After taking each lesson once, there is no chance that you can remember all the vocabulary, grammar and conjugations. You may think that it would be better to learn more vocabulary, but in my experience it is very useful to have to basic vocab from Duolingo instantaneously available. Just try to have a Spanish conversation. If you find that you need to think for minutes about each sentence, go back and repeat all the lessons.
