Hi all,

I've notice a few days ago that the long waited for exercises in multivariable calculus are coming. If i open the main page of the course i can read the following

"Practice content is coming! We will update this course with about 50 new exercises and some new articles as well. The course will also be mastery enabled, so you will be able to track your progress. And you will keep your progress in any of the videos or articles where you’ve already worked."

but i can't find any "official" information about it. Are you aware of a recent post about this where KA staff gives us more information?
