The Duolingo's Greek course is brilliant, it'd be even more brilliant if it had very simple grammar notes... 
...so I added very simple grammar notes, so simple in fact even I understand them.

 Content updates: 

• Unit 30 (Explorer 22) - present participle (incomplete)
• Unit 29 (Explorer 21) - directions
• Unit 28 (Explorer 20) - places

Download files update:

• Alphabet and Vocabulary
• Grammar Table
• 200 Useful Verbs List

Other:

• Two minor correction - in the alphabet chart and the pronouns chart
• Quick tables reordered for easier usage.

If you find any errors or archaic forms in the grammar tables, please let know, my snap and mail are in the footer.

The blog is not optimised for mobile phones - tables and images don't scale properly on smaller screens. 

You can use and download whatever you want for whatever needs you have, I'd appreciate if you link the blog but don't fret too much about it.
