CorePath 9
Read full descriptionHide full description
CorePath 9 is a study studio built around Guided Paths (Subject → Topic → Session). Each session presents one focused task—reorder steps, spot an incorrect line, match terms, check units, or write a short justification—followed by an explanation of why the answer works and why a common alternative fails. Every session requires a saved PathNote (versioned v1/v2/…), and incorrect attempts create MistakeCards that shape Revision Mode focus sets and Studio Runs.
ChronoAtlas 9

ChronoAtlas 9 is a Grade 9 history and geography learning studio centered on student writing. Each session follows a guided flow: reason through a prompt, explain ideas in your own words, complete a short self-check, and save the result as a reusable study note. Progress comes from saved explanations—not endless quizzes or score screens.
