Would someone mind explaining how the score ranges work for Mastery Paths? If a student, completing the initial quiz in the example below, achieved a score of 3 would they be placed on the bottom or middle quiz?

When I look at the Mastery Paths breakdown (image on right), the score of 3 is in both ranges (0pts to 3pts AND 3pts to 5pts).

I've read the guides and watched relevant clips and their screenshots also appear to have overlapping scores.
