Track recap
Compact review built from the authored track order and the same local-first concept progress already saved in this browser.

How it works
Same authored sequence, lighter revisit.
Recap mode does not invent a second curriculum. It keeps the existing starter-track order, then changes the prompt and suggested action with the current mastery and progress signals.
Keep using concept pages
Quick tests, challenge mode, worked examples, and read-next stay where they already live.
Recap links only jump you to the most useful surface for a fast review. The simulation-first concept pages still carry the real teaching work and keep the guided path intact.
Recap steps
Revisit the track in the same authored order.
Focus badges and button targets come from the current mastery and progress signals. The next ready checkpoint still stays in the loop.

Stoichiometric Ratios and Recipe Batches
Stoichiometric Ratios and Recipe Batches is still the next guided step in this authored order. No finished quick test, solved challenge, or completion mark is saved yet.
Start here before moving into Limiting Reagent and Leftover Reactants.
