I love the update you've made @khanacademy. I have a few questions: can a student still reach 100% mastery by completing just the "missions" section in their course? All of my 100% students from last year are now registering as 72% in the new progress screen (grade 6).
Re: Q1 “Can a student still reach 100% mastery by completing just the missions section?” Our new system was designed to require that a student gets 100% on all the units AND 100% on the course challenge (which didn’t exist in missions) to achieve 100% mastery for a course. (1/2)
