Most of my math skills in Khan Academy are below 100%, but when I go to the missions, the mission is at 100%.
I used to go to the world of math to target all the skills simultaneously, but even the world of math mission is at 100%.
In the world of math, I have 1496 skills mastered and nothing unmastered, which is last year's numbers and doesn't match with this year's skills. This year I'm missing a bunch of skills that I can't access.
I really hope this change isn't permanent. That would be horrible for my students.
