Post-Mock Review
- Build a top-ten list of missed terms and write each in a full environmental sentence.
- List every math error by unit type: percent, rate, area, energy, population, or dimensional analysis.
- Rewrite one FRQ using this order: identify the problem, explain the mechanism, propose a solution, justify the result.
Do not judge the mock by score alone. The best output is a repair map for the next seven days.
