Learning Klingon is so much fun. It is really hard though. I started it and I could not stop.
In some ways Klingon is actually an easy language, but it is very different from English and that makes it difficult to learn. You have to teach your brain to understand language in completely new ways.
Many users do not even know that there are Tips that explain the difference and help make things easier. If you are trying to do the course without reading the Tips, that will be very hard, indeed!
Duolingo has hidden the Tips so I want to make sure you know about them and where to find them. If you have not been reading the Tips, I would like to ask that you review those.
If you are doing the course on iOS or Android, you cannot currently access the Tips through the app. To access the Tips, you will have to access the course using a web browser at https://www.duolingo.com/. You can still do it on your mobile device, but you will have to use the web browser instead of the app (or you can do it from a computer). When you click on a Skill, it will expand to reveal a Start button and a Tips button.
If you click on the Tips button it will reveal the Tips and give you a detailed explanation of the grammar that is introduced in that Skill. If you have questions after reading the Tips for any Skills, we are happy to answer your questions, but many of your questions will probably already be answered in the Tips.
