It sounds like this is a new difficulty that started with Khan Academy Reimagined.
If you have been using Khan Academy in your classroom both before and after the change, would you be willing to post your feedback in the post I made to accumulate teacher feedback on Khan Academy Reimagined?

(I'm just another user, and I don't know if KA will use the feedback, but I think it's worth trying.
I don't remember seeing a single comment in the Support Community that says a teacher likes anything about the change. I've seen several saying they dislike aspects of it, and several saying they really want the old interface back.
I don't even know if KA had any classroom teachers test KA Reimagined; maybe KA staff just guessed what teachers wanted based on Support Community posts.

If far more classroom teachers dislike the changes than like them, KA should roll them back.)

I agree completely! Has anyone found a workaround?

I really need students to see their assignments scores. I hope KA will update so students can see their progress on exercises.

I just submitted a feedback on the website for this exact issue. I want my students to score 75% or above. But it only shows them the score immediately upon completion, then disappears to revisit later. I hope they fix this soon!!!

lgamato,

Where did you submit the feedback?
