Ratings and Reviews
Skill level does not work!
Had to download this app for school and it's horrible. The skill level does not increase when I get 9 in a row, but of course drastically drops when I get an answer wrong. There have been a couple instances where the class has done an assignment but it will not submit, or the teacher cannot access out scores.
Sorry for the issues you faced in the app. We have fixed the bug that prevented the assignment scores from being reported to the teacher. You can contact us at firstname.lastname@example.org if you are facing any other issues with the app.
could use modifications
One thing I wish you could do is select skills that have been assigned but past the due date, and turn them in. This app has made me want to die, it is that bad,
Really good and informative app.
With Family Sharing set up, up to six family members can use this app.
