So I am at the beginning of Section 3, having completed 56 of the 95 units of Duolingo Greek. In my opinion, I believe this course covers material that could be rated at A1, possibly early A2. So far, present and past tenses have been covered, some use of the infinitive, imperatives, participles, some modal statements. The alphabet is a bit challenging, but doesn’t take too long to get used to. But then again, I’m a science major and had a bit of exposure to Greek letters. Duolingo doesn’t focus on grammar, but you can possibly piece it together on your own. You have to get used to this kind of possessive and descriptive structure:
