These pages group existing concepts, tracks, topic pages, and challenge checkpoints into a clear sequence. Start here when you want structure without browsing all concepts first.

Goal-based guided paths
Keep the first scan short, then open the authored paths only when you need a clearer objective.
Start on the waves topic page, keep the Waves Evidence Loop compact, and reuse the authored wave order before widening into the rest of the branch.

Use the electricity topic page, the authored bridge lesson set, and the main electricity track when the field-to-voltage-to-circuit handoff should stay explicit.
No saved progress yet inside Electricity.
Use the electricity topic page, the existing electricity-to-magnetism bridge collection, and the magnetic starter track so the transition into electromagnetism stays bounded and transparent.
Electricity is the authored prerequisite for Magnetism. Electric Fields opens this track and sets up the rest of the path. Nothing is hard-gated here; this is simply the authored prep path.
Use the functions topic page, the new lesson set, the compact math starter track, and the calculus topic page so graph moves, rational asymptotes, exponential change, local slope, and accumulation stay on one coherent bench.
No saved progress yet inside Functions.
Use the vectors topic page, the new bridge collection, the short bridge track, and the mechanics topic page so vectors feel like one language before motion problems take over.
No saved progress yet inside Vectors.
Use the complex-and-parametric topic page, the new lesson set, the compact starter track, and the vectors topic page so the plane language widens from complex numbers into unit-circle and polar-coordinate geometry, then deepens into trig identities and inverse-angle reasoning before motion.
No saved progress yet inside Complex Numbers and Parametric Motion.
Use the chemistry topic page, the new Rates and Equilibrium Lesson Set, the compact starter track, and the thermodynamics topic page so the chemistry pilot feels like a real branch instead of isolated concept links.
No saved progress yet inside Rates and Equilibrium.
Use the stoichiometry-and-yield topic page, the new lesson set, the compact starter track, and the solutions-and-pH topic page so chemistry quantities stay visual instead of becoming detached worksheet algebra.
No saved progress yet inside Stoichiometry and Yield.
Use the solutions-and-pH topic page, the new Solutions and pH Lesson Set, the starter track, and the rates-and-equilibrium topic page so Chemistry feels broader without becoming sprawling.
No saved progress yet inside Solutions and pH.
Use the algorithms-and-search topic page, the new playlist, the compact starter track, and the frontier-state revisit so the CS branch stays bounded while it grows into graph traversal.
No saved progress yet inside Algorithms and Search.
Guided collections by format
Lesson sets and playlists stay grouped so the page reads like a guided entry point instead of a flat CMS export.
Use these when you want a short authored sequence with one obvious next move at each step.
Use these when you want a looser bundle of related simulations without the full topic-map overhead.
10 guided paths
Each one stays short and focused instead of trying to be a full course.
43 ordered steps
Steps can send you to concepts, tracks, challenge checkpoints, and other existing pages without duplicating content.
55 covered concepts
Coverage still comes from the same core concepts used across the rest of the site.
1,079 estimated minutes
Time estimates stay approximate so you can judge the size of a path quickly.
