You started as a beginner in Latin, and used Duolingo...
You completed the tree, and after that, did you read Latin texts? Which ones?
Do you have the feeling you understand the language (or almost)? What's your opinion about your progress?
Also: I'd like to ask if someone knows the free Latin school by postmail?
I started the course 16 days ago and I've just completed (reached the 5th level) the skill market. After completion of the whole tree, I plan to continue learning with the textbook Lingua Latina per se Illustrata.
At the moment, the tree covers the level A1 only which means a beginner. Thus I do not expect to be able to understand the language at that stage.
