Track recap
Compact review built from the authored track order and the same local-first concept progress already saved in this browser.
Start with concentration and dilution in one beaker, then reuse that same solution language to read acid-base balance and pH.
Recap mode stays available, but it becomes useful after you save some local progress in the track.
How it works
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
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
Focus badges and button targets come from the current mastery and progress signals. The next ready checkpoint still stays in the loop.
Concentration and Dilution 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 Acid-Base / pH Intuition.
This concept stays in the recap because it completes the authored track story, even if you have not reached it on this browser yet.
Capstone step after Concentration and Dilution.
