Sophia - Calculating Grade

[lacussucceed]

There are the the normal challenges and the milestones. Milestones count double.
I think most challenges give you 3 attempts already and for both challenges and milestones: check the materials.

You can miss out on 332 - 233 points (70%, rounded to be sure) = 99 points. So you can indeed fail 99 normal challenge questions or 49 milestone questions since they count double.

Be sure to check the tab "Score Report" to ensure the scores are ok.

I don't have the correct breakdown, but let's assume
9 challenges each 12 questions = 108 questions = total 108 points
4 milestones each 28 questions = 56 points = total 224 points
------ +
332 points total
