Students can't see their scores anymore

I've been using Khan Academy for years in my Math classes.  I setup my classes and give students assignments.  In the newest version, the students don't even get a score or a record of what they've done.  Once they do an assignment, it disappears and marks it as "completed," even if they get 0 questions correct.  Even if they go to the completed section, it doesn't tell them a score.  Do we really expect students to remember what score they got on an assignment and know which ones they need to re-do?  There needs to be a "score" page somewhere.  Otherwise it's useless to me and I'll have to drop Khan from my routines.
