Sorry I wasn't very clear in my first post. DS8 completed the Pre-Algebra assessment and his Pie was shown as 70% completed. His gaps were mainly in
Functions & Graphs, Exponents & Polynomials,Proportion,%, Data Probability and
Geometery.

He completed 100% for the rest.

After the "test", I realised that he could only continue to work on the "Pre-Algebra" course (till mastery) before moving on to the another course. Or is it possible to sign up more than one course at the same time?

I think I was kind of disappointed as I thought the initial assessment will help me see what are the gaps for DS in general (without having to select a Course myself). So if he continues to finish the Pre-Algebra, should I move him back to Grade 3? or Grade 5? or ??
