FAQ

Common questions

What does Mark Buddy cover?

Mark Buddy focuses on Math: grade-level NYSED practice, SHSAT preparation and ISEE Upper Level Quantitative Reasoning and Mathematics Achievement.

Can my child work on paper?

Yes. Students can complete questions online, or print a worksheet and upload their handwritten answers for marking.

How does Lumi track readiness?

Lumi combines results by topic and shows exam-specific evidence. Readiness uses every topic's reference-sample weight; topics without evidence contribute zero. It is a practice measure, not a predicted official exam score.

What do faint percentages mean?

Faint means fewer than 10 questions from the selected exam format in that topic. Full colour means at least 10. Topic accuracy includes completed questions across exams.
