Overview

🎯 Focus Next

Confirmed gaps whose prerequisites are already solid, ranked by leverage — how much this unlocks, minus how much it needs. Nothing appears here unless the student is genuinely ready for it right now. Click a row to see its prerequisite chain.

Reading the map

Border color = topic domain. Each box fills from the bottom as questions get answered (3 = a confident read); the fill's color is the mastery tier once there's enough to judge. Hover a topic for the exact %. A gold top-right badge with a rank number means it's on the Focus Next list.

Save your progress

Downloads a file you (or the family) can keep and reload later to pick up right where this left off — useful for spreading a longer assessment across more than one sitting. Name it anything you like; it's just a label, not shared anywhere.
