It's in the tips and notes.
how to get tips and notes:
organized by skill in one pdf for the whole course: https://www.docdroid.net/JnfmyEV/tipsnotesbackup.pdf
Replace your username where USERNAME is for information on your progress & the tips & notes: https://duome.eu/USERNAME/progress (This is my favourite way).
The whole course tips and notes are here (and the site has one for each Duolingo language): ,organized by skill individually: http://duolingo.wikia.com/wiki/Hebrew
You can also get them on the duolingo.com site (make sure your browser is in desktop view mode so you can see the other duolingo features like discussions & timed practice (the language clubs are only on the app though). From discussions you can search for all the discussions in this course (like this one you're reading, as well as see general duolingo discussions). If you can't see discussions on the top of the main screen once logged into duolingo you're not in desktop view.
