I find it frustrating when duolingo does not tell me when i typed something incorrect. in this example I wrote "schwarte pferde" instead of schwarze pferde" and I was not corrected. so now I second quess all my answers. not sure how i can report this.
I posted my screenshot using this site: https://postimages.org/
Even though there are certain issues with Duolingo I still think it is a great way to learn a foreign language. My thanks and appreciation to the volunteers.
How am I supposed do answer these kind of questions without any former lessons in the lessons's tip section? There is nothing about the strong inflection in your tips... I had to check it in the forum and other resources which is annoying and this makes paying for the premium account worthless.
Please provide us more complete lesson tips. Regards
