Suggested next sub-lessons from your Mastery Engine, ordered by what you're most ready for. Use each sub-lesson's AI Support to warm up on its prerequisites, practise it, or get a lesson.
Your Mastery Engine
The content you've chosen to master. Add or remove any track, course, lesson or sub-lesson with its + / ✓ — removed sections stay in the bank (and in every program) and appear here dimmed so you can add them back. Browse programs from + Customize.
Programs
Everything you enrol in is a program. One that follows one source keeps that source's order — watch a lesson, quiz it, finish the program. Others are built by an admin from lessons across many courses toward a goal. Nothing is copied: mastering a lesson anywhere counts everywhere it appears.
