Section scores tell you nothing new
A 610 in maths tells you maths is the problem. You knew maths was the problem. It is a summary of a thing you already had, printed in the largest type on the page.
The subscores are the plan
Heart of Algebra, Problem Solving and Data Analysis, Passport to Advanced Math. Three numbers, and between them they say which of three courses the missing marks came out of. That is the difference between *do more maths* and *do these twelve question types*.
Cross-test scores are noise
Ignore them. They are assembled from questions already counted somewhere else and they do not point at anything you can practise.
Turn it into four weeks
Take the lowest subscore, find the question types underneath it, and work only those until a timed section moves. Then take the next one. Four weeks a subscore is a term, and a term is what most students actually have.
